surface of the earth at the earth's north magnetic pole

I cannot solve Part B. I've looked at numerous solutions on Chegg with an answer of 6.2 * 10^8 A but that is incorrect. I have tried 6.0,6.1,6.3 as well. Any help with Part B would be greatly appreciated.

Show transcribed image text The earth's magnetic dipole moment is 8.0 times 1022 Am2. What is the magnetic field strength on the surface of the earth at the earth's north magnetic pole? You can assume that the current loop is deep inside the earth. Express your answer to two significant figures and include the appropriate units. Astronauts discover an earth-size planet without a magnetic field. To create a magnetic field at the north pole with the same strength as earth's, they propose running a current through a wire around the equator. What size current would be needed? Express your answer to two significant figures and include the appropriate units.
