ECONOMIST: Recreating the planet's magnetic field in a laboratory

Andrew Kent, a physicist at New York University, spends most days running electricity through a magnet smaller in diameter than a single cell, trying to determine the lowest current at which an electron's spin changes orientation.

As the train's magnets pass over a frame, they induce an electric current in it and this, in turn, generates a magnetic field which repels the magnet that started the whole process and thus levitates the train.
