Since the boom of the NdFeB magnets industry, the usage and potential applications for permanent magnet machines have grown exponentially to the detriment of traditional induction systems. In special ...

In January 2001, it was announced that MgB2 (magnesium diboride), a compound that was well known to chemists, was superconducting up to 39 Kelvin. Building on this discovery, Hyper Tech was formed in ...

Trees and forests are an incredibly important natural resource — not only for lumber and agricultural products, but also because they maintain a huge amount of biodiversity, stabilize their local ...

The latest in-line shaft generator from ABB is designed to enable ship operators to benefit from the multiple advantages of permanent magnet technology. The new generator brings flexibility and ease ...

Damping vibrations is crucial for precision experiments, for example in astronomy. A new invention uses a special kind of magnets to achieve this -- electropermanent magnets. They consist of a ...

High frequency Helmholtz coils are often used to generate uniform but time varying high frequency magnetic fields for a number of applications such as magnetic field susceptibility, calibration, and ...

How many of you plan to build a wind-powered generator in the next year? Okay, both of you can put your hands down. Even if you don’t want to wind your coils manually, learning about the principles in ...
