The magnetic field and angle of dip at a place on the earth are

0.3 G

and

3 0^{\circ}

, respectively. The value of the vertical component of the earth's magnetic field at the place is ____.

Answer: $0.15 G$ .

The vertical component is

B_{V} = B sin δ = 0.3 \times sin 3 0^{\circ} = 0.3 \times \frac{1}{2} .

B_{V} = 0.15 G
