Question

At a certain place, the angle of dip is 30 ° and the horizontal component of earth's magnetic field is 50 μT . The total magnetic field (in μT ) of the earth at this place, is, 100 3 μT, 100 μT, 100 3 μT, 200 μT

MARKS App · Accepted Answer

B = H cos ⁡ δ = 50 cos ⁡ 30 o = 50 × 2 3 = 100 3 μT (H = horizontal component of the earth's magnetic field and B = total magnetic field of earth)
