WebDefining magnetic flux density Typical magnetic field strengths: Earth’s field bar magnet MRI magnet B ~50 mT 0.1 T 0.2 – 3.0 T Fleming’s left-hand rule: Force on the wire is perpendicular to both l and B. Electromagnetism Electric currents have loops of B flux around them. Current-turns produce flux. WebThe 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, a "magnet."
