A short bar magnet is placed with its north pole pointing 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 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 short bar magnet is placed with its north pole pointing south. The neutral point is 10cm away from the centre of the magnet. If H=0*4 gauss, calculate magnetic moment of the magnet.

A bar magnet is placed with its north pole towards geographic north. The neutral point

The magnetic moment of a short bar magnet is 1*6Am^2 . It is placed in the magnetic meridian with north pole pointing south. The neutral point is obtained at 20cm from the centre of the magnet. Calculate the horizontal component H of earth's field. If magnet be reversed i.e. north pole pointing north, find the position of the neutral point.

A very small magnet is placed in the magnetic meridian with its south pole pointing north. The null point is obtained 20 cm away from the centre of the magnet. If the earth's magnetic field (horizontal component) at this point be 0.3 Gauss, the magnetic moment of the magnet is

A short bar magnet is placed along N-S direction with N pole pointing north. The neutral points are located 20 cm away from the bar magnet. If B_(H) is the horizontal component of earth's magnetic field then the magnetic field due to the bar magnet at distance of 40 cm along its axis is

A bar magnet is placed with its North pole pointing North. Neutral point is at a distance 'd' from the center of magnet. The net magnetic induction at the same distance on the axial line of the magnet is

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 .
