Hello everyone, excuse for my bad english, I am trying to make a transformer whitout the core, but only with the 2 inductance, is it possible? I think yes because a variable f e m in inductor produces an electromagnetic field that can be combined with another inductance. My big problem is the law and formulas to make this ( the distance between the inductance, the values of components).
Thanks very much.

Bye

 

I think what you are going to do is a air-core transformer, right? So for this purpose the best solution in my opinion is the Tesla Coil. The Tesla Coil is a resonant, high-frequency step-up transformer used to produce extremely high voltages. Is this what am you looking for? If not let me know. I will think of something different. Also if you need any help to make the Tesla coil let you, k. Hope it would help you.
