A metalic ring connected to a rod oscillates freely like a pendulum. If now a magnetic field is applied in horizontal diection so that the pendulum now swings through the field, the pendulum will

A metallic ring is connected to a rod oscillates freely like a pendulum. If now a magnetic field is applied in horizontal direction so that the pendulum now swings through the field, the pendulum will

One bar magnet is suspended so as to rotate freely in horizontal magnetic field. Then .....

A simple pendulum oscillates freely between points A and B. We now put a peg (nail) at some point C as shown. As the pendulum moves from A to the right, the string will bend at C and the pendulum will go to its extreme points D. Ignoring friction, the point D

A conducting rod of 1 m length and 1 kg mass is suspended by two verticle wires through its ends. An external magnetic field of 2T is applied normal to the rod. Now the current to be passed through the rod so as to make the tension in the wire zero is [Take g = 10 ms^(-2)]

A simple pendulum with a bob of mass m and a conducting wire of length L, swings under gravity with an angular amplitude 2theta . If the horizontal component of the earth's magnetic field perpendicular to the plane of motion of the pendulum is B, then the maximum emf induced across the pendulum is
