The intensity of the magnetic field due to the Earth at a point inside a hollow steel box is:

The horizontal component of the earth's magnetic field at any place is $0.36 \times 10^{-4} \; Wb/m^2$. If the angle of dip at that place is $60^{\circ}$,then the value of the vertical component of the earth's magnetic field will be ........ $\times 10^{-4} \; Wb/m^2$.

The Earth's magnetic field at the equator is approximately $0.4 \, G$. Calculate the Earth's magnetic dipole moment (nearly). (Radius of Earth $R = 6.4 \times 10^6 \, m$)

If a magnet is suspended freely such that it can rotate about its magnetic axis,in which plane does it come to rest?

What is the angle between the axis of rotation and the magnetic axis of the Earth (in $°$)?
