The Electric Motor
⭐ MasteredAn electric motor changes electrical energy into movement using magnets and coils. Motors power fans, washing machines, electric cars and robots.
Michael Faraday made one of the first motors in 1821.
All about The Electric Motor
An electric motor changes electrical energy into movement. When electricity flows through a coil of wire placed in a magnetic field, the coil experiences a force that makes it turn. This is the basic principle behind motors used in fans, washing machines and cars.
Michael Faraday demonstrated early electric motors in the 1820s, and later inventors improved them. Electric motors are efficient and quiet, and they are used in everything from toys and robots to trains and electric vehicles.

Frequently asked questions about The Electric Motor
What is the difference between a motor and a generator?
A motor turns electricity into movement. A generator turns movement into electricity.
What is a magnetic field?
An invisible area around a magnet or electric current where magnetic forces can be felt.
Are electric motors more efficient than petrol engines?
Yes. Electric motors convert a much higher share of energy into movement, with less waste as heat.
