That is exactly correct, in fact this is about the opposite of electromagnetism. In electromagnetism they use electricity to make a magnet, here they use it to create motion.

i think it is under electromagnetism. im pretty sure it is

What would this experiment be defined as? Would it be under electromagnetism?

Oops, These were replies to previous posts. Clearly, I have yet to master the procedure for commenting on youtube.

if I push something, will it move towards me?

I don't have sound working on my computer yet, so I don't know what he said, but: You're wrong. This doesn't necessarily have anything to do with induction or electromagnets. It has to do with the Lorentz force that describes the force on a moving charge in a magnetic field. More loops -> more moving charges -> more torque -> coil moves faster. Or if you could reduce the resistance in the wires you get faster moving charges -> more torque -> coil moves faster

my question is, is it possible to spin a dynamo without using any outside source, like ; wind ,or water, or fuel like gas , and how about if I'm going to spin the dynamo using it's own energy to spin it self. can it be possible ?

The wire is insulated with plastic so the electrons have to go in a circle.

OMG It's so easy to make!!! Actually when I was 7 I use to make this cind of stuff...
