A detailed experimental analysis explains the forces by which a spinning magnet can cause another magnet to levitate in midair. An experiment with off-the-shelf components uses a magnet glued to the ...

Goudsmit Magnetics, based in Waalre in the Netherlands, has launched a rotating Cleanflow magnetic separator that can be cleaned without stopping production. It is compatible with free-fall lines in a ...

A low-power Faraday rotation spectroscopy (FRS) nitrogen dioxide (NO 2) sensor basing on ring array permanent magnets was proposed by researchers led by Prof. Gao Xiaoming from the Hefei Institutes of ...

Electricity and magnetism are closely related: Power lines generate a magnetic field, rotating magnets in a generator produce electricity. However, the phenomenon is much more complicated: electrical ...
