Question

A bar magnet is freely suspended in such a way that when it oscillates in the horizontal plane

Answer 1

Answer:

Explanation:

A short bar magnet placed in a horizontal plane has its axis aligned along the magnetic north-south direction. Null points are found on the axis of the magnet at 14 cm from the centre of the magnet. The earth's magnetic field at the place is 0.36 G and the angle of dip is zero.

Answer 2

Answer : a bar magnet is freely suspended in such a way that when it oscillates in the horizontal plane it makes 20 oscillations per minute at a place where dip angle is 30 degree and 15 oscillations per minute at a place where dip angle is 60 degree.
