Question

What is the relation between angle of dip and magnetic latitude?

(a) tanδ=4tanλ

(b) tanδ=\(\frac {4}{tan \lambda }\)

(c) tanδ=\(\frac {2}{tan \lambda }\)

(d) tanδ=2tanλ

The question was asked during an interview for a job.

My enquiry is from Earth’s Magnetism in division Magnetism and Matter of Physics – Class 12

Answer 1

Right answer is (d) tanδ=2tanλ

Best explanation: If a magnet is freely suspended or inclined or dipped, the angle between the horizontal and the angle of inclination of the magnet that is inclined only by the earth’s magnetic field will indicate the magnetic latitude. The relation is as follows:

tanδ=2tanλ
