The magnetic moment of the assumed dipole at the earth's centre is `8.0 xx 10^22 A m^2`. Calculate the magnetic field `B` at the geomagnetic poles of the earth. Radius of the earth is `6400 km`.

Calculate the electrical capacitance of earth. The radius of earth is 6400 km.

The earth’s magnetic field lines resemble that of a dipole at the centre of the earth. If the magnetic moment of this dipole is close to 8 x× 10^(22) Am^(2) , the value of earth’s magnetic field near the equator is close to (radius of the earth = 6.4 × 10^(6) m)
