Indian Rope Trick Project #72
Do you feel like a magician?
Part A: Secure the magnet in place with nothing
beneath it. Tie a paper clip to the string and place it
on the magnet. Slowly pull the string away so the
paper clip is suspended in air. Hold the paper clip in
place with a weight, as shown.
Next, hold the magnet near the paper clip and lift it
off the ground, without it touching the magnet. Move
it around in mid-air.
Part B: Build the circuit shown and place the iron
core rod in the electromagnet (M3). Secure the paper
clip-string with a weight above the circuit, as shown.
Push the press switch (S2) to pull the paper clip
towards the electromagnet. Attract and release the
paper clip by pressing and releasing the switch.
