Motors

What's a Motor

A motor is a contraption that has a current carrying wire and magnets. In this case, we made motors out of wire, magnets, and battery. The current carrying wire, current from battery, feels a force in a magnetic field and the force causes a rotation, or torque. This is how my motor worked.
*A motor has current bearing wires and magnets.

My motor looks like the one in the picture above. It span freely on its own in the paper clips and the paper clips plus the other materials all helped the motor become a motor.

The paperclips were attached to the ends of the battery, they were used as the stand and conduct current to the wire. The wire was the current carrying wire that span as a result of the current flowing, since it was in a loop. The magnet supplies the change in magnetic field which causes the torque, and the battery supplies the current for the whole contraption.

The Making

To make this fully functional, I had to scratch the arms (paperclips) and the wire in a certain way. I made the paper clips in a certain way, like the picture, to hold the wire freely in the hole and scratched to allow current to flow through the wire. Now the wire was scratched on one certain side to also allow the current to go through freely. This is because the copper on the wire tops (the coating) would cause no current to go through and if we scratched it all over, it wouldn't make a complete circle when spinning. (right hand rule applies here).

This wire spins because of the moving charges and current going through it. The magnetic field is going up, the current goes across the wire, and so the force of the loop is to the side of the wire, which creates a torque and spins the loop.(Again, the right hand rule)

All of these moving charges feel a force from the magnetic field and they move away in such a way to the field, perpendicular. 

One whereabout you can find a motor like such is in an engine. Thick wire, when you turn on the current will cause a spin to the propeller and cause the push against the water so the boat can accelerate forward, or back.
