Project 93 Circuits Fun
Build the circuit as shown, set the meter (M5) to the
1A setting, and place the magnet as shown. Turn
on the slide switch (S1); the white LED (D6) lights
and the meter measures the current. Set the
switcher (S6) to the top position to make the fan
spin, set it to the bottom position to make the fan
spin faster, or set it to the middle position to turn off
the fan. The compass is attached to the magnet;
push the press switch (S2) to make the compass be
attracted to the electromagnet (M3).

WARNING:
Do not lean over the motor.
Project 92 Magnetic Switcher
Build the circuit and turn on the slide switch (S1); the lamp (L4) should
be on. Hold the magnet near the reed switch (S9) to activate the relay
(S3), which turns the white LED (D6) on and the lamp off.
