Q)

A short bar magnet placed in a horizontal plane has its axis aligned along the magnet north - south direction . Null points are found on the axis of the of the magnet at 14cm from the center of the magnet . The earth magnetic field at the place is 0.36G and the cycle 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 (14 cm) from the centre of the magnet?

(i)magnitude : 0.54 G (ii) direction : along the direction of earth's field(i)magnitude : 5.4 G (ii) direction: opposite to the direction of earth's field (i)magnitude : 0.54 G (ii) direction along the direction of earth's field (i)magnitude : 0.54 G (ii) direction along the direction of earth's field
