Why are charged particles influenced by magnetic fields? Is it the charicteristic charge itself that the field interracts with (positive or negative) or is there something else about the proton or electron that is inherent within it that interracts with the field.
Charged particles like electron, if at rest, produce only electric field but if they start to move with a certain velocity then they produce a magnetic field in addition to the electric field.
Charged particles are not influenced by a external magnetic field if they are at rest.
But when they move they produce their own magnetic field and eventually, a magnetic force appears on the charge due to their interaction with the external magnetic field.
