Wanted to see if magnetic motors were legit
 

I have no idea the extent of the use of magnetic fields in the development of motors but I had to try something for myself.

This came from a youtube video I previously watched about alternative energy, etc. It looked to0 good to be true so I tried it...



Can you imagine what some precision and manufacturing could do with this kind of technology?

You know that all electric motors are magnetic right?

Perpetual motion machines, more specifically the Howard Johnson motor and derivatives are nothing but a scam. :2 cents:

I know they are... but I suggest you try that same setup with whatever magnet you can find and make that fucker spin like that.

The only perpetual thing I have ever heard of that is real is a perfect tank circuit

The battery is the source of energy... it is not perpetual motion because of that.

I am not saying it is something that never stops... but really... that thing was moving so fast before it toppled. Obviously it toppled because I bent everything by my hand... science it... precision it... that thing will spin like a mother fucker.

How long does a remote control battery last on one of those little helicopters? 10 minutes... I have not tested this long enough because my weights are all off but I think this thing would last hours... something to think about.

Yes, it will spin until it runs out of energy then it won't spin anymore until more energy is available to be consumed.

Right... I'm not saying it is perpetual... I am saying that the magnet used below the battery is crazy strong... introduced in the last 15 years or so... and technology is not using it.

Guess the magnet?

A rare earth magnet will do this with a battery, rare earth magnets have commonly used applications such as wind turbines.

There's nothing here which isn't already being exploited in technology that is all around us.

AK... something is making you think I posted a revolutionary concept never before scene.

I saw the thing on youtube and wanted to replicate it... which I did.

I will say that nobody in mechanical engineering, aerospace engineering, etc. is taking it seriously from what I have seen. They are still gung ho about rocket propulsion. Science advancements are a complicated animal...

I can guarantee you any electric motor purchased in the US (and likely Australia) do not have the magnet incorporated that is in my video... below the battery.

Probably the Chinese are doing something with it.

you are trying to hard to believe this.

Believe what? That magnetic fields can cause a tornado like effect which then creates motion...

I just think it is the coolest thing and I think most of science, in general, is retarded :thumbsup

All of our planes fly with jet fuel harvested from dead dinosaurs... lol

... and as cool as the concept of a flying bird back to the wright brothers... after 100 years dont you think mimicking a bird flight is enough?

he is using very strong magnet, aka neodymium magnets.

they last way longer than regular magnets, they are expensive too.
you can get them on amazon/ebay watch for frauds/.

Dinosaurs were just an intermediary - the energy came from the sun.

''Thanks..now I gotta edit the sound because of the bitch in the background''.

Loving it.

But beaner,

you are crazy to think we don't already have such technology. Nothing new will come until oil is dead dead dead.

electric engines are future, but when oil is dead

You are now our leading scientist. Expect an interview request from Sleezy soon.

Hi Beaner,

This was a cool trick learned back in electronics class in high school. All electric motors work the same way, including this one. You're not seeing any new technology or any kind of perpetual energy or anything like that. The energy source is still the battery, and it will stop spinning when the battery is drained. It's cool looking, not its not magical or exotic.


If you want to see something really, really cool, watch this video:



But don't be fooled by the word "levitates" in the video descriptor. What you will see is "Quantum Levitation of a Super Conductor". and "Quantum Locking" It's 10 minutes long but really worth watching if you like cool science.

Sun => plants => fuel.

And make sure to rub them on your credit cards and hard disks for good luck!

Necessity is the mother of all invention.

Yeah... that was cool. From what I could understand he created a magnetic field, then cooled a lesser metal which had a bit of a magnetic field which locked it. Something like that.

I'm not sure what high school is doing electric motors with neo magnets. Notice how the setup in my video has no full circuit connection? I am not a motor builder by any stretch of the imagination but I remember doing some fun little tests way back but am fairly certain it included a copper wire connecting both the negative and positive of the battery to make it work.

Also, if I were to flip the magnets, it would spin the other direction. That is rather obvious though since you are changing the polarity.

^^Exactly... I said in my first post I saw it on youtube. Mine just spins a lot faster.

But... it is the neo magnets creating an anomaly where there is not a positive and negative connection required. The copper only needs to touch either the positive, or the negative, terminal of battery. Something with the strength of magnet allows the current (I believe) to pass through the air. It will NOT work with your regular home depot magnet.

All of these neo youtube videos have recently been popping up. It was not something from 20 years ago.

Finally, what I want to test is how long the battery will last with this setup. I think it will last a long ass time. Problem is, my setup is off centered, I need bearings to eliminate some of the screw/battery connection friction, etc.

.... or if someone knows of an electric motor with this same concept... neo magnet, copper only touching one terminal, battery that is in production? Then I don't need to test shit... I can just read up on it.

Basically I want to know if this setup will give the battery a longer life. Maybe this is very common now in electric motors... I sure can't find anything about it.

beaner, very very sorry, but you are wrong there...

1) There is a electric circuit, the magnets are conductors and your copper hits the magnets randomly.

2) The fact that all 4 of your copper strands are not connected constantly to current is actually the only reason why it turns. Because if all 4 sides were connected at once, it would sit still. This way, the tumbling automatically randomly turns on and of fields in each of the 4 sides, effectively making it possible for the magnets to push it into rotation.

3) The magnets are nothing special at all, they are simply strong magnets. This way the field in the copper does not need to be so strong and it still works.

4) The speed of your "motor" is nothing special at all. You have a motor with virtually no work attached. It will always be fast. It will also quickly drain the battery. The amount of HP or kW your motor produces is tiny!

5) How tiny? Simple: Your battery has 1.5V and usually has a standard drain of 50mA under typical usage. In your copper motor setup, not sure how much drain. But lets pretend 50mA (0.05A). That's a staggering 0.075W produced... 0.000075kW or... 0.0001hp.

Also, your battery will drain in roughly 40 hours.

As you noted, the other samples people have posted turn slower. Because 1) There is less copper per side and 2) there are less sides. If you increase your sides to 6 your motor would turn even faster if well balanced.

EVERY ELECTRIC MOTOR on this planet works this way. This is NOTHING special.

A motor consists of a strong constant magnet and a changing magneting field inside or around it. This field constantly shifts so that the resultings two magnets (one static, one changing) can push eachother away If it would be constantly on both, you would push the magnets away and when they get to the other side they would attract and just stick together. but by having 2 or 4 sides, and turning on one, having it pushed away, turning it off when it gets close to the other end and turning on the other one which will in turn be pushed away, creates a motor...

Sorry, you simply built a very simple motor...

:winkwink::thumbsup

BTW, re your question about power and battery life...

The work being done today to make electric motors more efficient has to do with:

1) less loss in friction and similar other forces.
2) Bigger batteries with higher power density
3) Batteries that can be charged faster.

In general though, a battery has X amount of energy and a motor converts this energy into rotational forces or torque and horsepower. Horsepower is nothing else than work, which is Watts. Watts = Volt * Ampere. So, a 1.5V battery that stores 2000mAh (like your AA does) will NEVER EVER be able to generate more than 1.5V*2000mAh = 3000mWh or 3Wh. Just as an example, a 200 horsepower petrol engine, is the same as 150kW or 150000W. So to power an electric engine that generates 200horsepower of work for 1 hour straight, or 150kW for 1 hour straight would require 150kWh of energy, or 150000Wh of energy, or the equivalent amount of energy as in 50000 AA batteries.

This is physics. It can not be changed or pushed "better" this is AS GOOD AS IT GETS. This is actually WORSE in real life since you have losses everywhere.

Well sheetz... I don't know... saw it on youtube and yes, seems to be a very common and simple motor not used because the amps it draws. Way more energy then justifies the motor.

...HOWEVER...

I am telling you, I just tried it again and pulled apart the bottom so no way it touched the magnet. It started spinning right away.

I also ran down the first battery... took about 12 minutes to kill it.

no energy is being created...only consumed...from the battery...second law of thermodynamics...

And upon further inspection I think it does touch... double sheetz :1orglaugh

So I created a homopolar motor, discovered in the 1800's, and it sucks as a motor because it pulls too much from the battery?

Nathan,

What about a solid copper sleeve... would that rotate the fastest? Or is it really just the number of off/on connections at the magnet connection?

You liked that little comment :1orglaugh:1orglaugh
She was pissed as all hell because I was playing :thumbsup

Though I still believe magnetic forces and whatever energy source is the future of many things, including flying, my little experiment was just a replication of homopolar motor invented in 1800's :1orglaugh:1orglaugh

Now I have all these strong magnets and need to figure out what to do with them. They work great on the fridge. They didn't cost that much... $10 for 10 1/2" and $12 for 80 1/4"... includes shipping

Try swallowing them.

totally!

the motor is just an electric motor thought.

That's just a simple electric motor which you were leaned in the school course of physics when you were a kid. This effect is being used in all classic electric motors since 1821 :2 cents:

Don't nobody tell him about inductance or we're gonna see a new technology by beaner that no one is using and can get you 50% plus more joins *guaranteed*.

First off, it does not suck because it pulls too much from the battery. I was not sure how much load it would create, since I never checked, and I did not know how much load the battery can take. You basically took the max drain possible from it, which is why it only took 13 minutes to deplete.

Re the sleeve, no, it would not turn at all. It would generate one continuous field.

A copper sleeve would be like connecting pos to neg with a wire. When the circuit completes it must dissipate at the rate of the conductor/load allowed by the rate of the electrical source.

Right, just means it will get very hot. Depending on the direction of current, I just think (although I might be wrong, can not really wrap my head around the magnetic fields built) it might be shot off of the battery due to the two magnetic fields?

Might be completely wrong there though..

Here's another fun experiment for you. Wrap a small copper wire around a nail a hundred times or so then connect a 9volt battery to the ends of the wires.

You just made a controllable magnet and now are a little further along in your motor skills. Have luck.

If the fields don't flop due to outside manipulation, like square wave or something they would just get hot.

Speakers do ok because of that principle. Of course that's more a sin wave.

Professor Eric Laithwate designed a linear motor model that is the basis for everything from bullet trains to rail guns. Amazing shit when you can remove hinderences like friction.

Good morning. Just wanted to say that the copper never got hot at all... the battery did and so did the magnets.

Professor Paully, in lamens terms... is linear motor in is simplistic form a N/N or S/S magnet? You seem to be up to snuff on electric motors (may have no clue with billing... :) ) but seem to know about motors.

My goal was to create a core spinning with whatever means... then have outer shell spinning from center core without anything actually touching. So magnets with polarity facing eachother to create that motion. Would be great to be directed to a system that already works like that.

I have a reason for this... and it is very stupid but I have too much time on my hands :thumbsup
