Homework Statement
The Earth's magnetic field is essentially that of a magnetic dipole. If the field near the North Pole is about , what will it be (approximately) 1.4×104 above the surface at the North Pole?
Homework Equations
Apparently we need to use the Biot-Savart Law which I'm not sure how it even applies in this situation granted that Earth's magnetic field acts like a dipole.
The Attempt at a Solution
If anyone could give me a heads up on how to do this, that'd be great.
