SQ: This loop is located near a powerful magnet. The loop and the magnet are stationary. What will happen? Exploration: Test out the seed question with a magnet and coil (the coil will amplify the effect of a single loop.) Obtain a cow magnet, single test lead and an ammeter. Make several loops with your test lead and connect to the ammeter. Use a voltmeter if your ammeter is blown: either will work. Now observe the ammeter when the magnet moves. What happens? Organize your results using the table: Magnet Coil motion Current in coil? motion Stationary Stationary To the right Stationary Stationary To the right To the left Stationary Stationary To the left Other tests… What is going on here? What is it that induces a current in the coil? Be specific! your magnet hang down from a thread to determine its Let’s look at things more closely: Let north pole. Mark that pole with a piece of tape.
