This experiment shows Magnet +conductor+Motion=Current
Consider a coil of fine insulated wire wound on a plastic or
cardboard tube. Connect the ends of the coil to a DC milliammeter or
galvanometer (for demonstration purposes!). A center-zero meter is
preferred for this demonstration. Now take a bar magnet and thrust the
magnet into the coil. The meter will deflect. Now withdraw the magnet.
The meter deflects the other way. As we insert and withdraw the magnet,
the meter deflects from one side to the other. With the magnet
stationary, the meter reads zero. What’s happening? We see that when the
magnet is moving, a current is induced in the coil. The moving magnetic
field, from the moving magnet, cuts the conductors forming the coil.
Please use a sensitive VU meter or Galvanometer.
