Think about it: have a controlled magnetic field in the region of the spinning helicopter blades, and have the blades or some part of the spinning apparatus be a magnetic material. The constant rotation in the field will supply a potential difference – free electricity for the helicopter.
Now I’m not sure of the logistics or anything, but isn’t the concept definitely something to think about?

Ummm no….
That’s just more resistance the blades will have to overcome.
It already has "free" electricity from the alternator like device.
Here’s an idea of how they work. Much less drain on the Engine.

A fluctuating magnetic field with important avionics within that field?? bad idea….

Look at ‘Lenz’s Law’ and you will see that as current flows in the generator it becomes harder to turn, using the power that would otherwise be used to make the helicopter fly.

no, bad idea. Thee is no such thing as free electricity.
And the rotor and hub system in a copter is already extremely complicated. You don’t want to add to it.
