In their physics lab this week, students explored Faraday’s Law, a principle that describes how magnetism can create electricity. Starting by wrapping a length of wire around a PVC pipe, each lab group connected the ends of the wire coil to a voltage detector so that they could see when, or even if any electricity was created. After taping a small, powerful magnet to the end of a pencil, one student tilted the PVC pipe at a very small angle while another student dropped the pencil-magnet through the coil. They discovered that this created electricity! With each successive run, the lab groups would tilt their pipe at a steeper angle so that the pencil-magnet would slide down more quickly. In the end, the detected voltage increased as the magnet passed more quickly through the wire coil, just as Faraday’s Law predicted!
