Answer the following question regarding earth’s magnetism:

The angle of dip at a location in southern India is about 18°. Would you expect a greater or smaller dip angle in Britain?

The angle of dip will be greater than 18° in Britain. The angle of dip increases from equator towards pole. Britain is farther from equator as compared to India.

Note: The angle of dip increases from equator towards pole. At equator angle of dip is zero while at poles it is 90 degrees. The magnetic field lines are perpendicular at poles.
