In this topic, we are going to show you how to build an electric motor project ideas with battery, magnet and copper wire for your science fair project or exhibitions
There are many forms of Energy is available on earth. In that electrical energy also one form, it can be used to perform some work or convert to a mechanical energy
Electric motor work with electro-magnetic concept
Each magnet has the South Pole and the North Pole. Here like poles repel and whereas the opposite pole attracts each other.
Forces produced by magnetic field helps in producing a turning motion in electric motors.
When DC current from the battery is passed through a length of wire in a magnetic field then the wire will rotate. It is called a motor effect.
How does a homo-polar motor work
This electric motor making as two magnets, One is permanent magnet fixed on top of the battery. The second is the copper coil which becomes temporarily electromagnet when we pass electricity
When a copper coil becomes a temporary magnet, with the base permanent magnet.
The coils to start going align with the permanent magnetic fields. For example, if the base permanent magnet is set with the north pole and the coil will also set towards that. Hence the rotation occurs

Questions & Answers on Simple Electric Motor
- Which magnet is used in DC motor?
A permanent magnet DC motor uses permanent magnet which helps to create a magnetic field.
- Can two magnets make electricity?
Yes, two magnets make electricity. Magnetic field helps to pull and push electrons in some objects that are closer to them and hence making them to move.
- What is the use of free energy device with a magnet?
Natural properties of magnet poles such as attraction and repulsion help create perpetual motion.
- Do stronger magnets produce more electricity?
Yes, stronger magnets produce more electricity as it helps to generate a stronger electromagnetic field.
Conclusion for simple electric motor
Here we understand the working of DC motor using magnet, copper coil and flow of electricity due to the electromagnetic field.
