Horizontal component of earths magnetic field, BH= 0.16 G

Earth’s magnetic field at the given location = B

We can relate B and BH as:

Earths magnetic field lies in the vertical plane, 12°West of the geographic meridian, making an angle of 60°(upward) with the horizontal direction. Its magnitude is 0.32ss G.
