Question

Identfiy the correct relation. (BH =Horizontal component of earth's
magnetic field; By = Vertical component of earth's magnetic field and B =
Total intensity of earth's magnetic field)
B
Ву
BH
В — By XBн
B =
By + B;
B = BH + BV
I found an error​

Answer 1

Answer:

Horizontal and vertical components of earth's magnetic field are B

h

and B

v

, respectively.

We know that B

h

=B cosδ

where B is the earth's total magnetic field and δ is the angle of dip.

Also, B

v

=Bsinδ

⟹ B

2

=B

h

2

+B

v

2

⟹ B=

B

h

2

+B

v
