Question

Which of the following is not a correct statement for a magnet placed in the earth’s magnetic field ?
(a) Neutral points are always at an equal distance from the magnet.
(b) The position of neutral points depends on the direction of the magnet in the earth’s magnetic field.
(c) The position of neutral points does not depend on the direction of the magnet.
(d) The magnetic field strength is zero at the neutral points.

Answer

(c) The position of neutral points does not depend on the direction of the magnet.

Reason — As neutral points are the points at which two magnetic fields are equal in magnitude but opposite in direction, hence, the position of neutral points depends on the direction of the magnet. Therefore, the statement “The position of neutral points does not depend on the direction of the magnet” is incorrect.
