Lorentz force .

An electric charge will experience a force in uniform electric field. Similarly a moving charge experiences a magnetic force (Lorentz) in magnetic field. The SI unit of magnetic field intensity is defined in terms of Lorentz force. a. Write the expression for magnetic Lorentz force. b. Mention any two differences between electric and magnetic field. c. Give an account of work done by Lorentz force on a moving charge and corre sponding change in K.E.

Starting from the expression for the force on a current carrying conductor in a magnetic field, arrive at the expression for Lorentz magnetic force.

Write an expression in a vector form for the Lorentz magnetic force vecF on a charge Q moving with velocity vecV in a magnetic field vecB . What is the direction of the magnetic force?
