This is one of the simplest motors that a young student can make using a coil of magnet wire and a permanent magnet. Simple, yet it demonstrates a principle found in all motors that electrical current produces a magnetic field that in turn forces the motor to spin. The coil is made of 6 feet of 22 ga magnet wire wrapped around a D-cell. The coil is tied by twisting the ends of the wire around the coil directly across from each other. The wire is also used as the axel for rotation. The enamel coating is removed from the wire axels used to hold up the coil. The electrical current flows through the L bracket holding the coil up and then though the coil's bare wire contacting to the bracket. The motor converts electrical energy into mechanical energy.
