The elements of earth’s magnetic field at a place are declination, dip and horizontal intensity.The vertical component of earth’s magnetic field at a given placeis ,`sqrt3`times its horizontal,component. If total intensity of earth’s magnetic field at the place Is 0.4G, find the value of horizontal component of earth’s magnetic field.

The elements of earth.s magnetic field at a place are declination, dip and horizontal intensity. The vertical component of earth.s magnetic field at a given place is sqrt 3 times its horizontal component. If total intensity of earth.s magnetic field at the place is 0.4 G find the value of horizontal component of earth.s magnetic field.

Where on earth’s surface is the value of vertical component of Ihe earth’s magnetic field zero ?
