... • Now we know that the momentum (along the deflection direction) of disk A is the same in the frame initially at rest with respect to A and the frame initially at rest with respect to B. • But momentum is mass*distance/time. • The distances must be the same in both frames. (Why?) • The elapsed times ...

... We must underline the fact that the displacement current is not a real current, it is a timevarying electric field. The only reason for calling it displacement current density is that the dimension of this quantity coincides with that of current density. This phenomenon and equation is the symmetric ...
