Question

Buried at a point with geographical latitude 20degree N and the same longitude as the geomagnetic pole, at the depth of 200 m, is a sphere of 50 m radius of material with magnetic susceptibility contrast 0.5. The Earth's field is produced by a centered dipole titled 10degree from the Earth axis of rotation and magnetic moment m= 10^22 Am^2. Earth's radius os 6000 km. Calculate the anomaly produced by induced magnetization in the sphere (components B_r, B_ , and the total anomaly produced by the sphere B_sphere) at a point on the Earth's surface above the centre of the sphere in units of nT.
