At a certin place, the angle of dip is 30 degrees and the
horizontal component of earth's magnetic field is 0 50 oersted The
earth's total magnetic field is:

Jegannathan Anandaraman · Answer

Hello Pradeep, let B be the total magnetic field
Then B cos 30 = 0 5 oersted
So B = 2 / /3 * 1/2 = 1 / /3 oersted
B = 1 732/3 = 0 5773 oersted
