GEOLOGY

Detailed explanation-1: -When a charged particle-such as an electron, proton or ion-is in motion, magnetic lines of force rotate around the particle. Since electrical currentmoving through a wire consists of electrons in motion, there is amagnetic field around the wire.

Detailed explanation-2: -Magnetic forces can cause charged particles to move in circular or spiral paths. Particle accelerators keep protons following circular paths with magnetic force. Cosmic rays will follow spiral paths when encountering the magnetic field of astrophysical objects or planets (one example being Earth’s magnetic field).

Detailed explanation-3: -Moving charges or flow of charge causes magnetism. Notes of Moving Charges and Magnetism explain that magnetic fields further exert forces on the flow of charge, which in turn, exerts a force on other magnets. Such a phenomenon takes place because of the presence of consistent moving charges.
