This setup shows how an electric current can be produced in a coil by moving a magnet. A magnet is moved into and out of a large coil which induces a current in the coil. This is visible on the large galvanometer connected to the coil. The sign of the current changes as the direction of the motion changes.
* Equipment seen in the video may vary from equipment used in ND Demonstrations. See information and images below for ND equipment and setup.
Setup:
Place the large galvanometer on the lab table. Connect the red and black leads of the coil to the red and black jacks in the center of the galvanometer. Place the strong magnet on the lab table by the coil.
Move the magnet into and out of the coil to see the needle on the galvanometer move. When you move the magnet in the opposite direction, the galvanometer should read the opposite sign.
Notes:
It takes a very strong magnet to see a dramatic change in the galvanometer.
