Ashort bar magnet placed in a horizontal plane has its axis alignedalong the magnetic north-south direction. Null points are found onthe axis of the magnet at 14 cm from the centre of the magnet. Theearth’s magnetic field at the place is 0.36 G and the angle ofdip is zero. What is the total magnetic field on the normal bisectorof the magnet at the same distance as the null−point (i.e., 14cm) from the centre of the magnet? (At nullpoints, field due to a magnet is equaland opposite to the horizontal component of earth’s magneticfield.)

A
short bar magnet placed in a horizontal plane has its axis aligned
along the magnetic north-south direction. Null points are found on
the axis of the magnet at 14 cm from the centre of the magnet. The
earth’s magnetic field at the place is 0.36 G and the angle of
dip is zero. What is the total magnetic field on the normal bisector
of the magnet at the same distance as the null−point (i.e., 14
cm) from the centre of the magnet? (At null
points, field due to a magnet is equal
and opposite to the horizontal component of earth’s magnetic
field.)
