Question

13. If the horizontal and vertical components, at a
place,
are 0.3 oersted and 4 x 10-5 T respectively. What is
the total intensity of the earth's magnetic field ?
(Ans. 5 x 10-5T)​

Answer 1

Answer:

BH=0.3G, BV=0.52G

The earth's magnetic field

B=BH2+BV2=(0.3)2+(0.52)2=0.6G

and angle of dip, tanδ=BHBV=0.30.52=1.734

δ=tan−1(1.734)=60o.
