Question 202: Electromagnetic Induction

Question

A copper ring is held horizontally and a bar magnet is dropped through the ring with its length along the axis of the ring. The acceleration of the falling magnet while it is passing through the ring is

Accepted Answer

When the magnet is allowed to fall vertically along the axis of loop with its north pole towards the ring, the induced current in the ring consistently produces a magnetic force that opposes the magnet's motion relative to the ring, resulting in an upward force that counteracts gravity, reducing the acceleration of the falling magnet. Therefore, the acceleration in the magnet is less than g .

Answer

more than acceleration due to gravity.

Answer

less than acceleration due to gravity.

Answer

depends on the diameter of ring and length of magnet.

Answer

depends on pole strength of magnet.
