A straight wire carrying 5.1 A current is laid in a E-W magnetic field. When 0.28 m of wire is in the field, the wire feels a force of 3.3 N. What is the strength of the magnetic field?

Write maxwell's equations and discuss the terms involved and the results of each equation in classical electrodynamics. if it is possible to write these equations in integral form, give the integral forms. find the wave equation for electromagnetic waves from the maxwell equations. what is the propagation velocity of electromagnetic waves in space according to the wave equation you find?
