Calculating Magnetic Induction of Moving Planar Condensator

[Physworld]

Summary:: A planar condensator with the distance between the plates d, is moving with velocity V. The charge fidderence is U. Find the magnetic induction B, between the plates during the motion

I have solved this problem, but I am not sure about the solution, can anyone, please, tell me if I am right.

Your solution is based on your equation qvB = F_el. This is the expression for the magnetic force on a charge moving through a stationary magnetic field. Why do you think it would be applicable here? I think this problem expects you to consider two opposite currents and the magnetic field generated in the region between the two.

BTW, what is a "charge fidderence"? Is it like "covfefe" but in cgs units?
