If a charged particle at rest experiences no electromagnetic force, then electric field in that region

If a charged particle kept at rest experiences an electromagnetic force,

In an electromagnetic wave, the electric field is …….

If a charged particle goes unaccelerated in a region containing electric and magnetic fields,

A charged particle is moved along a magnetic field line. The magnetic force on the particle is

A point charge is brought in an electric field. The electric field at a near by point

If a proton is moved against the coulomb force of an electric field :

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.

If a charge is moved against the coulomb force of an electric field.

The electric and magnetic fields of an electromagnetic wave are
