Science Fair Projects for Kids
This fun video explains easy science fair project for kids. This project is about making a simple Homopolar Motor or also known as an Electromagnetic Motor. It explains the relationship between electric energy and magnetism.
Materials Required: –
- Copper Wire
- AA battery
- Neodymium Magnet
- Attach the neodymium magnet to the negative side of the battery.
- Bend the copper wire in three different shapes: – square, heart and a spiral.
- It should be bent is such a way that one end touches the positive side of the battery and the other one touches the negative end.
- The copper wire will begin to spin as soon as it touches the magnet.
A homopolar motor is a type of electric motor that uses direct current to power rotational movement, such as generated by the battery. It was first ever built and demonstrated by Michael Faraday in 1821. It uses Lorentz Force as the main concept which causes the wire to spin in a circle. A current of electrons is flowing through the wire.
