Build a Simple AC Generator— Classroom Set
Create power! In this simple, easy-to-make device, two powerful neodymium magnets spinning in a coil of wire induce a current. You can also use the device to show students the difference between direct and alternating currents.
Hand Generator
With a turn of the crank, conduct dozens of hands-on experiments to study electromag- netism, polarity, simple circuits, resistance and mechanical work. Nylon-plastic gears and color-coded cord and plug are designed for durability. Supplies direct current with an output of up to 12 volts and 200 mA.
