... opposes the cause of changing magnetic flux. Here, the cause of changing magnetic flux is due to motion of the loop and increase in area of the coil in the uniform magnetic field. Therefore, this motion of the loop is to be opposed. So, the current is setting itself such that by Fleming’s Left Hand ...

... We will assume that any medium is linear, so that D = E and H = µ1 B. First, compute the work done by the electromagnetic fields on a system of particles. For a single particle, we have the Lorentz force law, F = q (E + v × B) and this provides the entire basis for extending mechanical energy and m ...
