Project 91
Electromagnetic Playground
Build the circuit, set the meter (M5) to the 1A setting, place
the iron core rod in the electromagnet (M3), and place the
fan on the motor (M1). Turn on the slide switch (S1); the
white LED (D6) lights, the meter measures the current, and
the electromagnet attracts the compass needle. Set the
switcher (S6) to the left to the left to light the lamps, to the
right to spin the motor & fan, or the middle to do neither.
