Faraday's law for a coil is :
V = A * M * N
Where: V = Peak output-voltage A = Area of the cross-section of the wire M = Rate of change of magnetic flux in the coil N = Number of turns of the coil
Whats happens when A gets very small and N very large? I expect that in that case internal resistance gets higher and the output voltage drops??
If that's true, there will be a certain combination of A and N that will be optimal for a needed V. Question: How to obtain this A and N ?
NB: By optimal I mean minimal space needed by the coil and minimal material costs for the wire.
edit: The coil is used as a generator like in a bike dynamo. So the coil is wound around a linear weak-iron core.
