A magnet is suspended in the magnetic meridian with an untwisted wire. The upper end of wire is rotated through `180^(@)` to deflect the magnet by `30^(@)` from magnetic meridian. When this magnet is replaced by another magnet, the upper end of wire is rotated through `270^(@)` to deflect the magnet `30^(@)` from magnetic meridian. The ratio of magnetic moment of magnets is

A magnet is suspended in the magnetic meridian with an untwisted wire. The upper end of wire is rotated through 181° to deflect magnet by 37° from magnetic meridian. Now this magnet is replaced by another magnet and upper end of wire has to be rotated by 273° to deflect magnet by 53° from magnetic meridian. The ratio of magnetic moment of the two magnets respectively is

What is a magnetic meridian?

Magnetic meridian is an imaginary:

A bar magnet of magnetic moment M_(1) is suspended by a wire in a magnetic field. The upper end of the wire is rotated through 180^(@) , then the magnet rotated through 45^(@) . Under similar conditions another magnetic of magnetic moment M_(2) is rotated through 30^(0) . Then find the ratio of M_(1)&M_(2) .
