Write the components of earth magnetic field at any arbitrary point?

High energy charged particles rain in on the Earth from all directions, most of them produced by the Sun. If it weren’t for the Earth’s magnetic field we would be subject to bursts of radiation on the ground that would be, at the very least, unhealthy. The more serious, long term impact would be the erosion of the atmosphere. Charged particles carry far more kinetic energy than massless particles (light), so when they strike air molecules they can kick them hard enough to eject them into space. This may have already happened on Mars, which shows evidence of having once had a magnetic field and a complex atmosphere, and now has neither (Mars’ atmosphere is ~1% as dense as ours).
Rule #1 for magnetic fields is the “right hand rule”: point your fingers in the direction a charged particle is moving, curl your fingers in the direction of the magnetic field, and your thumb will point in the direction the particle will turn. The component of the velocity that points along the field is ignored (you don’t have to curl your fingers in the direction they’re already pointing), and the force is proportional to the speed of the particle and the strength of the magnetic field.

A vector is a quantity that has both magnitude and direction. Displacement, velocity, acceleration, and force are the vector quantities that we have discussed thus far in the Physics Classroom Tutorial. In the first couple of units, all vectors that we discussed were simply directed up, down, left or right. When there was a free-body diagram depicting the forces acting upon an object, each individual force was directed in one dimension - either up or down or left or right. When an object had an acceleration and we described its direction, it was directed in one dimension - either up or down or left or right. Now in this unit, we begin to see examples of vectors that are directed in two dimensions - upward and rightward, northward and westward, eastward and southward, etc.

The magnetic intensity of earth magnetic field makes an angle known as angle of dip with horizontal axis.
The intensity of earth magnetic field can be resolved into two components:horizontal component
Magnetic declination
Magnetic inclination or angle of dip
