Motors

·   What was the function of each part of the motor?

Battery – to provide the charge to the current carrying wire

Paper Clips – to hold the current carrying wire, and to stabilize it providing a base to sit on

Copper wire – acted as the current carrying wire, which spun.

Magnet – provided magnetic force to cause the current carrying wire to exert a torque

Rubber band – To hold everything together

·         Why did you scrape the armature in a specific way?

If the wire received power the entire time, it would not try to spin around to get away from the magnet, and would remain sedentary.

·         Why does the axle spin?

The axle spins, because the current in the wire if perpendicular to the magnet, and a magnetic force is produced with that, and so the force tries to exert a force in the form of a torque to rotate it.
