13. 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 fleld at the place is 0-36 G and the angle of dip is zero. What is the totan magnetc leld on the normal bisector of the magnet at the same distance as the null points (Le. 14 cm) from the centre of the magnet? (At null points, field due to a magnet is equal and opposite o the horizontal component of earth's magnetic field).

direction. Null points are found on the axis of the magnet at 14 cm from the centre of the magnet.
The earth's magnetic fleld at the place is 0-36 G and the angle of dip is zero. What is the total
magnetc neld on the normal bisector of the magnet at the same distance as the null polnts (Le.
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).
