Question

The angle of dip at a place on the earth gives :

• A. The horizontal component of the earth's magnetic field.
• B. The location of geograhical meridian.
• C. The vertical component of the earth's magnetic field.
• D. The direction of the earth's magnetic field.

Answer 1

The correct option is D The direction of the earth's magnetic field.

The angle made by the earth's total magnetic field with the horizontal direction is called angle of dip at the given place.

The angle of D decreases from 90° to 0° as one goes from magnetic pole to the magnetic equator.

$tan\Delta =\frac{B_V}{B_H}$

The angle of dip at a place on the earth gives the direction of the earth's magnetic field.
