Electromagnet

An electromagnet is a temporary magnet created by passing an electric current through a coil of wire, which produces a magnetic field. It can be turned on and off by controlling the electric current, allowing for various applications such as doorbells, speakers, and electric motors.

Nail

In order for an electromagnet to work, a piece of copper wire needs to be wrapped around a metal piece. The nail is converted into a type of magnet by running an electric current through a coil of wire. It produces a magnetic field that can be turned on or off by controlling the current flow.

Battery

A battery is a device that stores chemical energy and converts it into electrical energy. When a battery is connected to a circuit, a chemical reaction takes place that releases electrons, creating an electrical current.

Copper Wire

Copper wire is used to make the coil in an electromagnet because it is a good conductor of electricity. When an electric current flows through the wire, it generates a magnetic field around it. The thickness of the wire, the number of turns in the coil, and the amount of current flowing through the wire all affect the strength of the magnetic field.
