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

Options:

Answer:

Solution:

$B = \frac{H}{\cos δ} = \frac{50}{\cos 30^{o}} = \frac{50 \times 2}{\sqrt{3}} = \frac{100}{\sqrt{3}} μT$

(H = horizontal component of the earth's magnetic field and B = total magnetic field of earth)
