In cases 6 and 8, there was no relative motion between OR and CM . Yet, a positive E occurred. In particular, case 8 is totally unexplainable by the Lorentz transformation of the fields. But this is unbelievable and useless as explained in PART 1. The rectilinear variation of Faraday's inductor proves the point.
Practical details follow.
5 and 6 were piled up forming four layers as shown in Fig. A gap between the two lower layers allowed inserting the insulated rectangular loop OECR . Finally, add plates PP' to confine the magnetic field totally within an iron yoke, as shown in Fig. I except that the motions are now inertial instead of rotational. This induction is located at OR and not at ECR , since the latter lies in a field free region and its motion is irrelevant.
