I wonder if we could engineer some material that does fulfill his spec. Magnetic in air, loses magnetic properties underwater, regains them when out of the water...

An electromagnet with no waterproofing. Stick it in water, it shorts out, once it dries out it starts working again.

That's fine but it would be better if a partially submerged device also functioned partially. And I said material specifically because it's lame if it needs power.
