German engineers create nano-sized radio transmitter using two disc magnets

The additional video below is quite amazing. The presenter demonstrates how to combine six small magnets with one larger magnet to create magnetic Lagrange points rather than gravitational ones. Magnetic field strength follows the one over distance cubed law rather than the one over distance squared law of gravitational fields.

this is pretty cool!

any ideas on the use of one though?

This is cool! The applications for this could be enormous I don't know if any of you have read Michael chritchon but his book micro lets us know what these could be used for.
