Paper Clip Oscillator (III)
Take a paper clip 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 control lever to the right. The paper clip
gets sucked into the center of the electromagnet
and stays suspended there. Move the adjustable
resistor lever to the left, and the paper clip falls.
Now for the fun part: Slowly slide the adjustable
resistor lever until you find a spot where the
paper clip is bouncing up and down. The speaker
(SP) makes a clicking sound.
