A short bar magnet with its north pole facing north forms a neutral point at `P` in the horizontal plane. If the magnet is rotated by `90^(@)` in the horizontal plane, the net magnetic induction at `P` is (Horizontal component of earth's magnetic field `=B_(H))`

What is horizontal component of the Earth's magnetic field ?

Explain the horizontal and vertical components of earth's magnetic field.

What is the value of the horizontal component of the earth's magnetic field at the poles?

At neutral point, the horizontal component of the magnetic field due to a magnet is

At neutral point,the horizontal component of the magnetic field due to a magnet is

A short bar magnet of magnetic moment 0*5JT^-1 is placed with its magnetic axis in magnetic meridian, with its north pole pointing geographic north. A neutral point is obtained at a distance of 0*1m from the centre of the magnet. Find the horizontal component of 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.
