Let the magnetic field on earth be modelled by that of a point magnetic dipole at the centre of earth. The angle of dip at a point on the geographical equator

A

is always zero.

B

can be zero at specific points.

C

can be positive or negative.

D

is bounded.

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
Angle of inclination is the angle between the direction of intensity of total magnetic field of the earth and a horizontal line in the magnetic meridian. If the total magnetic field of the earth is modelled by a point magnetic dipole at the centre then it is in the same plane of geographic equator, thus the angle of dip at a point on the geographical equator is bounded in a range from positive to negative value.
