In this magnetizing segment of Science Sunday, Mark and Aoife show you how to turn a magnet on and off, as well as highlight the different types electromagnets we encounter in our lives. Unlike a regular magnet, an electromagnet runs on electricity, which means you can change the strength of the magnet by controlling how much electric current flows through it. If you look closely at your environment, electromagnets are everywhere. Doors that require a card swipe to open often involve an electromagnet. When the card swipes through the reader, it temporarily breaks the circuit of electricity and allows the door to open.Â
