What do you mean by magnetic Lorentz force?
Asked by Topperlearning User | 19 May, 2015, 09:44: AM
answered-by-expert Expert Answer

When a charged particle moves in a uniform magnetic field, there exists the interaction between the applied magnetic field and the magnetic field produced by the moving charge. Due to this interaction a moving charge experiences a force, which is known as magnetic Lorentz force. It is given by expression

SI unit of Lorentz Force is Newton (N).

As we know, work done by Magnetic force is always zero in moving a charged particle./So it cannot change speed of charged particle. MY doubt is that, can magnetic force change direction of motion of charged particle?
