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; ...

A Chinese research team has set a new record for a flat-top pulsed magnetic field (FTPMF) with a whopping 71.36 tesla, further consolidating the nation's international leadership in this field. The ...

Physicists Prof. Dr. Ingo Rehberg from the University of Bayreuth and Dr. Peter Blümler from Johannes Gutenberg University Mainz have developed and experimentally validated an innovative approach for ...

When we think of powerful magnets used in particle accelerators or for NMR (nuclear magnetic resonance), we often envision bulky machines, sometimes the size of buildings. But in an extraordinary ...

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 ...

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 ...

A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and sizes ...

How can you produce a magnet with exactly the right magnetic field? A research team now has a solution: for the first time, they have created magnets with a 3D printer. Today, manufacturing strong ...

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 ...

Magnetic separation systems began appearing in scrap yards after World War II when heavy duty shredders used for grinding automobiles started to pop up across the United States. The early magnetic ...

This means that their magnetism is there all the time and cannot be turned on or off as it can with an electromagnet. Converting a magnet to a non-magnet is called demagnetisation. Magnets are made ...
