HW / motor

1.  Explain how/why the motor works.  It will be important to think about magnetic fields in coils.  In other words, why was it important to wrap the red wire into a coil?  What effect does that have on the magnetic field in the coil?  Is it similar to the electromagnet seen in class?

2.  Real motors are a bit more complicated.  Find images and/or descriptions of real motors, and comment on how they compare to yours.
