A motor consists of a current carrying wire and a magnetic field. In class, we made a motor out of a battery, a rubber band, paper clips, a rubber band, a copper wire, and a magnet.
In the motor, the battery created a current that moved through one of the paperclips, onto the copper wire, and to the other paper clip (on the other side). This made a complete circuit in which current was able to flow.
The battery supplies a current while the magnet supplies a magnetic field (b). The rubber band holds the paper clips in place and the paper clips allow the current from the battery to move to the copper wire. The paper clips also allow the wire to turn.
The copper wire has to be scraped on one side so that the wire will feel a force. The wire needs to be scrapped at the point of the paper clips to allow current through. If not done correctly, the wire will fail to make a complete circle when trying to spin.
The current carrying copper wire feels a force because it is in a perpendicular position to that of the magnet (on the battery). This force causes torque, thus, the wire will rotate and spin around.
This small battery could be used for a fun little fan or a small car for Stuart Little.
