Embibe Experts Solutions for Chapter: Matter and Magnetism, Exercise 1: JKCET 2017

In a bar magnet, the ratio of magnetic length to geometrical length is nearly

The equation $(\mathrm{tan\theta }=B_2/B_1),$ where $B_1$ and $B_2$ are magnetic fields perpendicular to each other represents

The deflections produced by a Tangent Galvanometer at two different places when the same current is passed through it are $45°$ and $60°$ respectively. The ratio of the values of ${\mathrm{B}}_{\mathrm{H}}$ at two places is

If ${\mathrm{B}}_{\mathrm{H}}=4\times {10}^{-5} \mathrm{T}$ and ${\mathrm{B}}_v=2\times {10}^{-5} \mathrm{T}$, then the Earth's total field at the place is (in $\mathrm{T}$):
