The bob of a simple pendulum is replaced by a magnet. The oscillation are set along the length of the magnet. A copper coil is added so that one pole of the magnet passes in and out of the coil. The coil is short-circuited. Then which one of the following happens

View answer and explanation

Correct option: C

Oscillations are damped

Option C (Oscillations are damped) is correct because the changing magnetic field induces a current in the coil, which opposes the motion of the magnet.

Curie temperature is the one above which A vibration magnetometer consists of two identical bar magnets placed one over the other such that they are perpendicular and bisect each other. The time period of oscillation in a horizontal magnetic field is

{2^{5/4}}

s. One of the magnets is removed and if the other magnet oscillates in the same field , then the time period in second is The relative permeability of a substance
