AI Thread Summary
The discussion focuses on the need for an equation that relates the number of turns in primary and secondary coils to the temperature increase caused by eddy currents. Participants suggest reviewing existing literature on transformers and eddy current losses to formulate specific questions. The importance of frequency over the number of turns in relation to heating effects, particularly in inductive heating applications, is emphasized. Induction furnaces can operate effectively with fewer turns, highlighting that the design parameters can vary significantly. Understanding these relationships is crucial for optimizing eddy current heating applications.

Welcome to the PF.

What reading have you done so far about transformers and eddy current losses? Can you post some links to your reading, and ask specific questions about the material in that reading? :smile:
 
Are you asking, "If I double the number of primary turns, how much does the eddy current rise?" (And the answer is, I don't know.)

No what if I want to utilize eddy current losses to have heating effect(inductive heating) so the relation for those parameters..

For heating frequency is more important than the number of turns. I've seen induction furnaces with less than ½ a dozen turns.
