Description

Electromagnetic Devices

Electromagnetic devices are tools and machines that use electricity and magnetism together to do work. When an electric current flows through a wire, it creates a magnetic field. By shaping the wire into coils or adding iron cores, this magnetic effect can be made stronger and useful. Devices such a...

An electromagnet is a type of magnet that turns on and off using electricity. For example, it can be made by wrapping copper wire around iron and letting an electric current flow through it.

When current flows through the wire, it creates a magnetic field that magnetizes the iron core, which can then attract objects.

When the current...
