A magnet is allowed to fall through a metallic ring.During fall what will
be its acceleration? (Less than g)Can a choke coil can be used as a
step-up and step-down transformer.Justify
If the magnet falls vertically through a metallic ring, then the magnetic flux through the ring increases thus inducing an emf in the ring. The induced emf will oppose the fall of the magnet and therefore the acceleration will be less than the acceleration due to gravity.
