ElectroMagnetic InductionHard
Question
A metallic ring with a small cut is held horizontally and a magnet is allowed to fall vertically through the ring then the acceleration of the magnet is :
Options
A.always equal to g
B.initially less than g but greater than g once it passes through the ring
C.initially greater than g but less than g once it passes through the ring
D.always less than g
Solution
Since, the ring is not continuous (due to the cut) there will be no current flowing in it. Now, as there is no current hence no force acts on the magnet due to the ring, other than gravity.
