Consider the plane S formed by the dipole axis and the axis of earth. Let P be point on the magnetic equator and in S. Let Q be the point of intersection of the geographical and magnetic equators Obtain the declination and dip angles at P and Q.

A

`0^(@)` and `11.3^(@)`

B

`0^(@)` and `0^(@)`

C

`113^(@)` and `6.5^(@)`

D

`11.3^(@)` and `11.3^(@)`

Text Solution

Verified by Experts

The correct Answer is:
A
P is in the plane S, needle is in north, so the declination is zero.
P is also on the magnetic equator, so the angle of dip = 0, because the value of angle of dip at equator is zero Q is also on the magnetic equator, thus the angle of dip is zero. As earth tilted on its axis by `11.3^(@)`, thus the declination at Q is `11.3^(@)`.

We can define two planes for a particular location on the surface of earth. One is called magnetic meridian and the other is called geographic meridian. Magnetic meridian for a point on the surface of earth is defined as a plane passing through this point and containing magnetic axis of earth. Similarly geographic meridian for a point on the surface of earth is defined as plane passing through this point and containing geographic axis of rotation. If we draw these two planes for a point on the surface of earth then in general these are found at some angle. Angle between these two planes is called declination for that place. Importance of magnetic meridian at a point is that net magnetic field vector of earth for that point lies on this plane. Usually net magnetic field of earth is inclined at some angle with the horizontal and this angle is called angle of dip for that place. How many points are there on surface of earth where angle of dip is 90^@ ?
