Magnet Motor Kit
Electric motors are everywhere; even your computer has electric motors to power its cooling fans and hard disks. Building a simple DC electric motor is a great way to learn how they work, and it's really fun to watch your creation spin.
The objective of this project is to build a simple electric motor from scratch.
How to make?
The next step is to prepare the axle supports. Use a pair of pliers to bend two safety pins from the middle. The safety pins can conduct electricity to the armature while the loops of wire on the safety pin can hold it up.
The base for this motor will be a wood block. It makes a nice base because it is heavy, stable and looks good for presentation in classroom or science fair. The wood block is large enough to hold the battery as well.
Use screws to mount the bent safety pins on the wood block so that the loops are faced to each other and about 1 inch apart.
Attach the wires from battery holder to the supports (bent safety pins)
Insert the battery into the holder. Place the magnet on top of the wood block just underneath the coil. Make sure the coil can still spin freely, and that it just misses the magnet.
Spin the armature gently to get the motor started. If it doesn't start, try spinning it in the other direction. The motor will only spin in one direction.
