Question

A short bar magnet placed on the table along the north south line. Its north pole is directed towards geographical north then the location of neutral points is?
A. North
B. South
C. East
D. West

Answer 1

In order to know the answer for this question we should be knowing the universal pointing directions. Also how does the magnetic field obtain for the bar magnet and which is compelling for the earth’s magnetic field.

Complete step by step answer:

According to above diagram when North Pole of the bar magnet points towards earth’s magnetic north, the null point is determined on perpendicular to bisector of the magnet.On the magnetic equator, the earth’s magnetic field is divided into two components that is horizontal component and vertical component on magnetic poles.The direction of the horizontal component of the Earth’s magnetic field is also called the direction of a magnetic meridian. Similarly magnetic field lines due to the bar magnet must be equal to the horizontal component of the earth magnetic field.

Hence, the correct option is (A).

Note: Usually the magnetic field is not the same for all the places. It is different at different locations. The magnetic field varies with place to place and time. The wide distribution of the magnetic field is measured by using satellites.
