. A short bar magnet has a magnetic moment of `2A -m^2`. If its magnetic length is 5cm, calculate its pole strength?

A short bar magnet has a magnetic moment of 2A -m^2 . If its geometric length is 6cm, calculate its pole strength.

A short bar magnet has magnetic moment 20 Am^2 . The axis of the magnet is in the magnetic meridian with the south pole pointing north. The horizontal component of earth's magnetic field at that place is 3 xx 10^-5 T. Find the point on the axis of the magnet at which the resultant magnetic field is zero, [such a point is called a neutral point].

A small bar magnet has a magnetic moment 1.2 A-m^(2) . The magnetic field at a distance 0.1 m on its axis will be: (mu_(0)=4pixx10^(-7)T-m//A)
