The motor performs a few different tasks:

• The Battery-Provides the electrical energy of the motor
• The coil of Wire-Carries current.
• The Paperclip-Connects and holds the coil of wire to the positive and negative ends.
• The Magnet-Aligns electrons in wire.

Joey scraped the outside layer of the wire (which will rests on the paperclip) in entirety at both ends of the wire.  We did this because if there was a steady current flowing through the wire the motor would not turn all the way around.  It would turn to halfway and then stop.  We scraped half of one side and the whole of another, which made it so that the the current would be across the the magnetic field would be up and the force would turn the motor. Therefore the motor would not be turned back flat after it was spinning we stripped half it would not be pulled flat and it would continue to spin around.

The Motor turns because the current is down the wire, the electromagnetic force is up, and the force spins the motor sideways.  If the wire was completely striped the force would flip and it would spin back resting sideways; because half of the wire is striped, the current will stop and the coil will flip the rest of the way around until the current reconnects.  By this time when there force on the motor it be in the right direction to spin the motor.
