A ring around the wings with fluid in it, and electric motors which pump the fluid to create a flywheel effect, could possibly eliminate the need for an extra tail rotor or a counter-clockwise moving rotor.

The ring could be lightweight and the fluid could be pumped in to the center of the helicopter or back out to the ring, as the rotor gains or loses lift.

Well, "centrifugal force" isn't the problem addressed here, and should just be erased.

Anti-torque through inertia?

The ring proposed would only be a useful counter-action to rotor torque as it starts up. As soon as the fluid inside reaches a steady speed, it won't do anything helpful. Pumping in and out wouldn't do anything except very temporarily, and that for only in or out, one.

Everything is inside the control volume.

Now what if the fluid was exxxxtremely magnetic ? The pilot's gametes may not like the enviroment though .

It wont do much, a tail rotor works because it works against the force of the main rotor... the fluid will work only as a stabilizing gyro, nothing else.

If the magnetism strong enough air molecules outside will feel effect and therefore generate waves sticky enough to counter main rotor . No ?
