DYNAMO

Magnatic field

MAGNETS

A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.

What is DYNAMO

A machine for converting mechanical energy into electrical energy, typically by means of rotating coils of copper wire in a magnetic field.
