Know the Answer?

Nora Rose · Answer 1

Its magnitude at the Earth's surface ranges from 25 to 65 microteslas (0.25 to 0.65 gauss). Roughly speaking it is the field of a magnetic dipole currently tilted at an angle of about 10 degrees with respect to Earth's rotational axis, as if there were a bar magnet placed at that angle at the center of the Earth.

Its magnitude at the Earth's surface ranges from 25 to 65 microteslas

(0.25 to 0.65 gauss).

How strong is that?

Strong enough to rotate a magnet to align with it, if the magnet is

free to rotate. But not strong enough to pull the paperclip off of the

corner of your home work.
