Answer:
There are three components that are responsible for the magnitude as well as the direction of the earth's magnetic field: Magnetic declination. Magnetic inclination or the angle of dip. Horizontal component of the earth's magnetic field.

explain three Earth magnetic elements??
The elements are:
1) Magnetic declination (q)
The small angle between magnetic axis and geographic axis at a place is defined as
magnetic declination at that place.
It is represented by θ
2) Magnetic inclination (d)
Magnetic dip, dip angle, or magnetic inclination is the angle made with the horizontal by the compass needle of a vertically held compass. This angle varies at different points on the Earth's surface. Positive values of inclination indicate that the magnetic field of the Earth is pointing downward, into the Earth, at the point of measurement.
3) Horizontal component (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.
