The equatorial meridian of a magnet ___________.
bisects the magnetic axis perpendicularly.
is parallel to the magnetic axis.
makes a certain angle with the magnetic equator.
contains both the pole of the magnet.
Hence, the equatorial meridian of a magnet bisects the magnetic axis perpendicularly.
The correct option is (A).
A bar magnet has a magnetic moment of 0.4 A.m2. On cutting it into two equal halves along equatorial line, each half will have a magnetic moment of :
The magnetic field strength at a point at a distance d from the centre on the axial line of a very short bar magnet of Magnetic moment M is B. The Magnetic induction at a distance 2d from the centre on the equatorial line of a Magnetic Moment 8M will be
