Magnetic clutch with
confined magnetic
circuit improves
mechanical coupling
between conductive cylinder and inner
and outer permanent magnets. Inner
magnet collimates
magnetic field in
the gaps maintaining
entire magnetic
field well confined.
This assembly should
be precursor of Tesla AsynChronous motor.
It is 3D: click it with
mice to rotate and
roll the middle button
to zoom, press it to
move around.
