A ships compass is mistakenly placed 8.35 cm away from a wire carrying a current of 8.25

Question:

A ship’s compass is mistakenly placed 8.35 cm away from a wire carrying a current of 8.25 A.

(a) What is the strength of the wire’s magnetic field on the compass?

(b) The strength of the earth’s magnetic field is 5.20 x 10^–5 T. How far from the wire must the compass be mounted so that it only experiences a magnetic field of 5.20 x 10^–7 T (1/100 of the magnetic field of the earth) due to the wire?
