A magnet is suspended horizontal in the earth's magnetic field. When it is displaced and then released it oscillates in a horizontal plane with a period T. If a place of wood of the same moment of inertia (about the axis of rotation) as the magnet is attached to the magnet what would the new period of oscillation of the system become?

A magnetic needle kept on horizontal surface oscillates in Earth's magnetic field. If the temperature of this needle is raised beyond the Curie temperature of the material of the needle, then ........ .

A dip needle vibrates in a vertical plane with time period of 3 second . The same needle is suspended horizontally and made to vibrate is a horizontal plane . The time period is again 3 sec. The angle of dip at that place is .
