Question

describe the elements of earth's magnetic field

Answer 1

Elements of the earth’s magnetic field are:

1.  Magnetic declination (θ): At a point on earth the magnetic meridian makes an angle with the geographic meridian. This angle is known as the magnetic declination or just declination.

2.  Angle of dip (δ): It is the angle made by the direction of the earth’s total magnetic field with the horizontal direction.

3.  Horizontal component of earth’s magnetic field (BH): It is the component of earth’s magnetic field along the horizontal direction.

So the angle of dip is the angle between earth’s magnetic field i.e. B and the horizontal component i.e. BH.

Hope, it helps you.
