In the magnetic meridian of a certain place, the horizontal component of the earth's magnetic field is 0.26G and the dip angle is `60^(@)`. What is the magnetic field of the earth at this location?

Text Solution

Verified by Experts

It is given that `H_(E)=0.26G`. From Fig 5.11 we have `cos 60^@=(H_(E))/(B_(E))`
`B_(E)=(H_(E))/(cos 60^(@))`
`=(0.26)/((1//2))=0.52 G`
