I like what some research has discovered with the use of plastics in everyday application of magnets. Adjustable magnetism!

It could expand into an entirely new propulsion/vehicle support mechanism. If it can be expanded to incorporate these issues, how could that be of benefit to our everyday commute? The possibilities have implications that exceed cpmmpn applications.

What do you mean by adjustable magnetism?

Researchers Develop World's First Light-Tunable "Plastic" Magnet

COLUMBUS, Ohio -- Low-cost, flexible electronics and better computer data storage might result from the world's first light-tunable plastic magnet, just developed at Ohio State University.
With colleagues at the University of Utah, researchers here developed a plastic material that becomes 1.5 times more magnetic when blue light shines on it. Green light partially reverses that effect.
Though possibly years away from everyday use, it still looks plausible for many applications.
