At the magnetic north pole of the earth 's the values of the horizontal copmonent H and the value the angle of dip `theta` are

A

`H = 0, theta = 45^(@)`

B

`H ne 0 , theta = 0^(@)`

C

`H = 0 , theta = 90^(@)`

D

`H ne 0 , theta = 90^(@)`

Text Solution

Verified by Experts

The correct Answer is:
C
At north pole , magnetic lines of forces of will be vertical and the magnet will be vertical (north pole pointing downwards) . Thus H = 0 and angle of dip `(theta)` is `90^(@)` at that place .
