Lorentz Force: If a charge +q is moving in an electric field E, it experiences a force qE called Lorentz electric force.If the charge q is moving in a magnetic field vecB , it experiences a force (vecvxxvecB) called Lorentz magnetic force. If charge q is moving in a n electric field E as well as in magnetic field vecB simultaneously, the total force experience by the charge is the sum of these two forces and is called total Lorentz force. If the charge is q is moving perpendicular to the magnetic field B, the work done by the magnetic field is
