The magnetic needle of a `V.M.M` completes `10` oscillaitons in `92`seconds. When a small megnet is placed in the magnetic meridian `10cm` due north of needle with north pole towards south completes `15` oscillations in `69`seconds. The magnetic moment of magnet

State the positions of neutral points when a magnet is placed with its axis in the magnetic meridian and with its north pole pointing towards the geographic north .

A bar magnet 30 cm long is placed in the magnetic meridian with its north towards south of the earth. If the neutral point is obtained 30 cm from the magnet, find magnetic dipole moment and pole strength of the magnet.

If we place a bar magnet in the magnetic meridian with its north pole towards geographic north, the neutral point will be :

A small magnetic needle performs 10 oscillations/minute in the earth's horizontal magnetic field . When a bar magnet is placed near the small magnet in same position , frequency of oscillations becomes 10sqrt2 oscillations/minute . If the bar magnet be turned around end to end , the rate of oscillation of small magnet will become
