Question

1. For a short bar magnet, magnetic field intensity at a point lying at the same distance from the center of magnetic dipole on the axial line of the magnet ( Baxial)is *

(a) equal to magnetic field intensity on the equatorial line (Bequatorial)

(b) twice the magnetic field intensity on the equatorial line (Bequatorial)

(c) zero

(d) four times magnetic field intensity on the equatorial line (Bequatorial)

​

Answer 1

Answer:

On the equatorial line of a bar magnet , the magnetic field is parallel to the axial line , so the perpendicular component is zero.
