Clearly demonstrate Faraday's law! Pass a magnet through a wire coil connected to an ammeter and the ammeter needle deflects-an electric current is produced. When the magnet stops moving, the needle returns to zero. Which of the three coils generates the most current and why? Students quantitatively compare the effects of changing variables such as magnet speed, coil number, and magnetic strength to the amount of current generated. Students can then determine if their results agree with Faraday's law.
Two kits are available. The Demonstration Kit includes all the materials needed to show Faraday's law on an overhead projector: 100-turn, 300-turn and 1000-turn coils, acrylic base, connector cords, low-current overhead projector ammeter, and detailed demonstration instructions. The Apparatus Kit is a stand-alone unit that includes all the same materials as the Demonstration Kit except the overhead projector ammeter and connector cords. A low-current (0-50 mA) ammeter is required for the Apparatus Kit.
