Permanent-magnet alternators (PMA or PM alternator) utilize permanent magnets instead of field coil excitation to generate electricity. PMAs offer high efficiency, low maintenance, and high ...

Magnetic reconnection is a process that occurs when the magnetic fields of a conductive plasma quickly rearrange and release ...

A novel experiment at the University of Hamburg utilizes matter waves to understand magnets. Magnets are built of elementary magnets which can point North (red) and South (blue), as can be seen in ...

Scientists demonstrated a contactless way to move and rotate conductive objects that could someday help robots safely handle ...
