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...
