|Sebald Justinus Brugmans, Michael Faraday electromagnetism|
In 1778, Sebald Justinus Brugmans, as a graduate student, found that bismuth and antimony were repelled by a magnetic field. * In 1845, Michael Faraday showed that diamagnetism was a property of matter, and all materials are either diamagnetic or paramagnetic.
A superconductor levitates above a magnet. Push and it pushes back. Ha, ha. Look, Ma, action at a distance.
No energy expended
A pyrolytic carbon wafer floats above a permanent ferromagnet with no expenditure of energy, which makes me wonder. Have I, all these years, have I been lazy, blind, and passed over the unexpected? .
