Electromagnets

An electromagnet is a type of magnet that produces a magnetic field when electricity flows through a coil of wire. When electric current passes through the wire, it creates a magnetic field around it, turning the coil into a magnet. When the current is turned off, the magnetic field disappears. Electromagnets are adaptable, as their strength can be controlled by adjusting the amount of electricity, and they are widely used in devices like cranes for lifting metal objects, electric motors, and relays. They are essential tools because they can be turned on and off and customized for specific applications.
