Question

a short bar magnet of moment 3.2 lies in the magnetic meridian with north pole pointing north B=0.4 gauss . the distance between the two neutral points is​

Answer 1

Answer:

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 in magnetic meridian with its north pole pointing

Answer 2

Answer:

Solution :

When north pole of the magnet points towards magnetic north, null point is obtained on perpendicular bisector of the magnet. Simultaneusly, magnetic field due to the bar magnet should be equal to the horizontal component of earth's magnetic field
