Day 20:

Magnetic motors and magnetic fields

Experitment #1:

Attaching the power supply to the motor caused it to spin, and reversing the current's direction causes it to spin in the opposite direction.

Magnetic Motor:

The motor that our group created was composed of copper wire, several magnets and paperclips, and a power supply. A symmetrical oval shape was formed from the wire. One lead was sanded down 360 degrees while the other lead was sanded down half that amount. The paper clips were used as mounting points for the copper wire and placed on the top of the cup, and a magnet was placed inbetween the contraption as shown above. The current from the power supply is what moves the current through the wire and causes it to turn.
