Given:

There are 4 wooden wheels, with their centers equidistant from each other, with a 100m loop of rope tautly connected between them.

Wheel 1 has a diameter of 1m.

Wheel 2 has a diameter of 5m.

Wheel 3 has a diameter of 3m, and has a magnetic torus(blue) attached to it.

Wheel 4 has a diameter of 5m.

Wheels 1 & 3 are parallel to each other, and wheels 2 & 4 are parallel to each other. These two pairs are perpendicular to each other.

There is a perfectly suspended loop of iron wire(red) where the diameter of that wire itself is 0.1m, the loop's diameter is just slightly larger than the 3m diameter of wheel 3 so that the wheel can freely turn.

What is the average induced emf in the iron wire if wheel 1 is being actively spun at 10 rad/second?
