For making this MAGNIFICENT MOTOR you will need a strong neodymium magnet, a 1.5-volt battery, a cycle spoke, wire and a piece of wood. Bend the spoke twice at right angles and screw it in the wooden board. The tip of the spoke should be sharpened into a point. Attach one end of an electrical wire to the frame.  
Stick a strong neodymium magnet to the base of a battery. Because of the strong magnet the battery button end will act like a magnet and will easily hang by the pointed spoke. Now touch the other end of the wire to the cylindrical surface of the magnet. This will complete the circuit and the magnet along with the battery will spin very fast like a motor. Sometimes the motor spins so fast that it is difficult to make out the spin.
So if you stick a paper clip to the magnet it will look like the blades of a fan and make the spin more visible. 
You can also make a geared motor by sticking a coin to the magnet. If the wire touches the larger diameter coin then the motor spins slowly. However, when the wire touches the lesser diameter magnet it spins much faster. This is like a GEAR mechanism.
