An electromagnet is an object that acts as a magnet when electricity passes through it. Electromagnets generally produce stronger electric force than a standard magnet.
Electromagnets come in many sizes and shapes. However, all electromagnets contain:
power source
copper wire
iron core

The wire coiled around the iron core of an electromagnet is called a solenoid. Solenoids cause electromagnets to produce stronger magnetic fields than electromagnets without solenoids. The more coils, or turns, in a solenoid, the stronger the magnetic force it will produce.
