Question

The horizontal component of the Earth's magnetic field measured in a vertical plane is B directed at an angle B with the horizontal. The vertical plane makes an angle a with the magnetic meridian.

A.The horizontal component of the Earth's
magnetic field at the place is B, B cos B cos a

B.The horizontal component of the Earth's magnetic field at the place is B, B cosa cos B

C.The dip angle at the place is S=tan sin B cosa cos B

D.The dip angle at the place is 8 = tan sin B sina cos B​

Answer 1

Answer:

The horizontal component of earth's magnetic field at a certain place is 3.0×10
