The evolution of industrial heating technologies has followed a fascinating path—from primitive open flames to complex magnetic fields. Today, induction heating stands at the forefront, offering ...

A primary voltage drives an alternating current through the primary coil. The primary coil current produces a changing magnetic field. This magnetic field changes as the current changes.

In other words, an alternating current is produced ... as this helped to concentrate the magnetic field.

Slip rings maintain constant contact with the same sides of the coil As one side of the coil moves up through the magnetic ... a current that is constantly changing. This is alternating current ...

Researchers at UTSA are developing a less invasive approach to treating Parkinson’s disease. Using magnetic nanoparticles and ...

In magnetic reconnection, adjacent magnetic field lines break and snap together to form new lines. This process converts magnetic energy to both thermal energy, or heat, and kinetic energy, or the ...

Now researchers at Nanyang Technological University (NTU) in Singapore have found a way to heat up resins using an alternating magnetic field (PDF), so-called magnetocuring.

A way to generate and control spin currents without magnetic fields or magnetic materials may be possible using dissipative quantum ratchets in the presence of spin–orbit coupling. But still ...
