Magnetic circuit

A magnetic circuit is like an electrical circuit, but instead of electricity flowing through it, a magnetic field is traveling all around it. The magnetic circuit is made up of a magnet and some material that the magnetic field can travel through, like metal. The magnetic field starts at the magnet and moves throughout the circuit, going in a loop and then back to the magnet. Magnetic circuits create electricity from the movement of the magnetic field, and can also be used to make things move, like motors.
