In other words, only if the coil wire cuts the magnetic lines of force, a voltage is induced into the wire. By the way, the wire must be insulated.

Does lemon juice clean copper?

Lemon Juice and Baking Soda Apply to the copper and buff with a soft cloth. Rinse with water and dry.

As gravity pulls the magnet downwards through the pipe, the magnetic field created by the eddy currents resist the magnetic field produced by the magnet, slowing it down.
