Question

The direction of the null points is on the axial line of a bar magnet when the north pole of the magnet is pointing.....

Answer 1

The direction of the null points is on the axial line of a bar magnet when the north pole of the magnet is pointing zero (null point).

Answer 2

Answer:

$\large\boxed{\sf{North}}$

Explanation:

• Basically Null point means the point where magnetic field strength becomes zero.
• If the direction of null point is on the equatorial line of a bar magnet , then North Pole of bar magnet faces to geographic north and south pole of bar magnet faces to geographic south.

Thus, the answer should be North .

• It means the direction of the null point is on the equatorial line of a bar magnet when North Pole of the magnet pointing to North .

Extra Knowledge:

• The magnetic south pole of the earth's magnetic field is at the geographic north pole and the magnetic north pole is at the geographic south.
• The magnetic field lines flow from north to south outside the magnet and south to north inside the magnet.
• When the north pole of bar magnet points geographic north , the null points are formed on the equatorial line at two points where magnetic field lines from the bar magnet are directed north to south, are cancelled by the magnetic field lines by the earth's magnet .
