Question 45: Magnetism and Matter

Question

At a certain place the angle of dip is 30$$^\circ$$ and the horizontal component of earth's magnetic field is 0.5 G. The earth's total magnetic field (in G), at that certain place, is :

Accepted Answer

$${B_H} = B\cos 30^\circ $$
$$ \Rightarrow B = {1 \over {\sqrt 3 }}G$$

Answer

$${1 \over {\sqrt 3 }}$$

Answer
