A bar magnet of magnetic moment M is bent in the form of quadrant of circular arc . The new magnetic moment is

If two identical bar mangets, each of length 'I' , pole strength 'm' and magnetic moment 'M' are placed perpendicular to each other with their unlike poles in contact, the magnetic moment of the combination is

Two bar magnets of magnetic moments 12Am^(2) and 10Am^(2) are placed one over the other .First with their similar poles in contact after unlike poles in contact.The ratio of their resultant magnetic moments is

The magnetic moment of a bar magnet is 0.256amp.m^(2) . Its pole strength is 400 milli amp. m . It is cut into two equal pieces and these two pieces are arranged at right angles to each other with their unlike poles in contact (or like poles in contact). The resultant magnetic moment of the system is
