A bar magnet of length 8 cm and having a pole strengh of 1.0 A m is placed vertically on a horizontal table with its south pole on the table. A neutral point is found on the table at a distance of 6.0 cm north of the magnet. Calculate the earth's horizontal magnetic field.

It is found that the neutral points lie along the axis of a magnet placed on a table. What is the orientation of the magnet w.r.t. the earth's magnetic field.

A short bar magnet is placed with its north pole pointin north. The neutral point is 10 cm away from the centre of the magnet. If H=0.4G, calculate the magnetic moment of the magnet.

A bar magnet of length 10cm is placed in the magnetic meridian with its north pole pointing towards the geographical north. A neutral point is obtained at a distance of 12cm from the centre of the magnet. Find the magnetic moment of the magnet, when H=0.34 gauss.

A bar magnet of length 0.1 m has a pole strength of 50 A m. Calculate the magnetic field at distance of 0.2 m from tis centre on its axial line

A bar magnet of length 0.1 m has a pole strength of 50 A m. Calculate the magnetic field at distance of 0.2 m from tis centre on its equitorial line.

A short magnet of magnetic moment 2.0 Weber-metre is lying in a horizontal plane with its north pole pointing 60^(@) east of north. Find the net magnetic field at a point north of the magnet 0.2 m away from it. Horizontal component of earth's magnetic field = 0.3 xx 10^(-4) T.
