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." WebSep 12, 2024 · The component of the velocity perpendicular to the magnetic field produces a magnetic force perpendicular to both this velocity and the field: (11.4.4) v p e r p = v sin θ (11.4.5) v p a r a = v cos θ. where θ is the angle between v and B. The component parallel to the magnetic field creates constant motion along the same direction as the ...
