As noted in the paper by [P. Helander] et al., the use of permanent magnets can substantially simplify the magnetic-field coils of a stellarator, which are then primarily used for the toroidal ...

“Focused” magnet system consisting of two stacked rings, each with 16 FeNdB magnet cuboids (side length 20 mm). The inner diameter is 160 mm, and the magnetic field of 20 mT exhibits a homogeneity of ...

Magnetic couplings transmit high torque with no physical contact, and they disengage smoothly when load gets too high. Generally speaking, the couplings use magnetic power in three different ways; ...

Permanent magnets are materials that generate a persistent magnetic field without needing an external source. Even after the removal of a magnetic force, these magnets can retain their magnetism for a ...

The global price of energy is at an all-time high, with few signs of relief in sight, making consumers and businesses alike interested in energy conservation. Currently, the most common motor type in ...
