A charge that is moving in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field.
Measure of quantity of magnetism taking account of the strength and the extent of a magnetic field.
A magnetic field is a vector field that describes the magnetic influence on moving electric charges electric currents and magnetized materials.
On platforms etc the electric fields come from the overhead catenary wire in systems with overhead electrification and the magnetic field comes from the current loop formed by the supply the overhead catenary or the third rail and the return the running rails or a dedicated conductor.
Earth s magnetic field also known as the geomagnetic field is the magnetic field that extends from the earth s interior out into space where it interacts with the solar wind a stream of charged particles emanating from the sun the magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in the earth s outer core.
