Ravindrakumar Yadav

Will you elaborate in detail?

Asking for which type of machine?

Newgato Chiro

Dear Ravindrakumar Yadav

Thank you for your answer. Attached bellow is an image that I hope will clarify the problem.

To elaborate a little on the subject :

We know what is the mutual impedance between two coils (filament circuits)

It is given by the double integral on both coils.

However my question here is what is the mutual induction between a coil and a plate where the currents in the plate are volume currents.

Thank you in advance.
