Faraday on Induction & Lines of Force

SOMETHING YOU DIDN'T LEARN IN SCHOOL

In Article 6 "General Remarks and Illustrations of the Force and Direction of Magneto-electric Induction, " paragraphs 217 & 218, Faraday questions whether it is necessary for there to be relative motion between the magnet an41 the. conductor to establish induction. According to the principles of electricity and magnetism as is taught in high schools and colleges, it is immediately evident that without magnetic lines of force (whatever they are) cutting the conductor, there would be no electrical current produced. Faraday took an ordinary cylinder magnet and cemented on the end a copper disk with insulating paper intervening. He reports: "...the magnet and disk were rotated together and the collectors ... brought in contact with the ... [rim and hub]. The galvanometer needle moved as in former cases. and the direction of motion was the same as that which would have resulted, if the copper only had revolved, and the magnet been fixed. Neither was there any apparent difference in the quantity of deflection. Hence. rotating the magnet causes no difference in the results." This basic experimental fact is seldom taught in either high school or college!

Knowing that an entergetic space pervades all space and manner, how would One explain magneto-electric induction? Here: is a suggested approach: A magnetic field aligns or modifies space energy such that if a conductor is moved through that modified space energy field. electrical current is caused to flow in the conductor. Note that this explanation says nothing about "cutting magnetic lines of force." This explanation implies, that regardless of how the space energy is aligned or modified the mere motion or rotation of a conductor, in that modified space energy field, will be sufficient to induce an electric current.
