I have two air coils. They both have diameter d. There is a distance D between their centres.
D is much greater than d (more than 10x greater)
Both coils are at different angles, a and b, relative to the line between their centers. There is an alternating current in one coil.
Is there some simple function which estimates the current induced in the second coil? I would be happy if the form of the function was:
k * f(D, a, b) (where k had to be measured)
For example: k * cos(a) * cos(b) * D^-2
