A free charged particle moves through a magnetic field. The particle is likely to undergo a change in :
Direction of motion
None of these
A free charged particle moving in a magnetic field experiences a force perpendicular to its direction of motion. This force does not affect its speed. Hence there is only a change in direction.
A charged particle of mass m charge q moving at a uniform velocity v enters a uniform magnetic field B normal to the field direction. Deduce an expression for Kinetic Energy of the particle. Why does the Kinetic Energy of the charged particle not change when moving through the magnetic field?
