Coils for electromagnets Patent US512340A
"In carrying out my invention it is to be observed that certain facts are well under-- stood by those skilled in the art, viz: the relations ot' capacity, self-induction, and the frequency and potential difference of the current.
sufficient to secure in the coil a capacity capable of neutralizing its self-induction ...in series and having a potential difference of such value as to give to the coil as a whole, a capacity sufficient to neutralize its self-induction, as set forth.
I have found that in every coil there exists a certain relation between its self-induction and capacity that permits a current of given frequency and potential to pass through it with no other opposition than that of ohmic resistance, or, in other words, as though it possessed no self-induction
I may wind any given coil either in Whole or in part, not only in the specic manner herein` illustrated, but in a great variety of ways,well known `in the art,
A consideration of the greatest importance in many cases, and the results, both as to efficiency and economy"
Infinite efficiency
Coil induction is why lenz law works so good against the rotor action. When Tesla eliminated a motors self induction he put an end to BEMF. Morgan burnt down his lab. This patent got under the radar as Tesla was now ducking for dear life.
