Construct a DC electric motor similar to the one shown earlier in Figure 11.8. Another DC motor that is very portable is shown in Figure 11.27. You can construct this using wire, two paperclips, a D-cell battery, and a small magnet. Use the battery as a form around which to wrap 10 to 15 turns of magnet wire. Both ends of the wire should have the insulation stripped off of one side. Put the motor together as shown. Start the coil moving by hand, and it should continue on its own.
