Paperclip Oscillator (III)
Take a paperclip and straighten it out, bend it in
half, and place it into the electromagnet (M3)
center. Turn on the slide switch (S1), and set the
adjustable resistor (RV) control lever to the right.
The paperclip gets sucked into the center of the
electromagnet and stays suspended there. Move
the adjustable resistor lever to the left, and the
paperclip falls.
Now for the fun part: Slowly slide the adjustable
resistor lever until you find a spot where the
paperclip is bouncing up and down. The speaker
(SP) makes a clicking sound.
