Earth magnetic field strength at surface
WebIn a sense, yes. The Earth is composed of layers having different chemical compositions and different physical properties. The crust of the Earth has some permanent magnetization, and the Earth’s core generates its own magnetic field, sustaining the main part of the field we measure at the surface. So we could say that the Earth is, therefore ... WebThe earths magnetic dipole moment is 8.0 x 10^22 Am^2. 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.
