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 ...

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 ...

A magnetic field is invisible, but it can be detected using a magnetic compass. A compass contains a small bar magnet on a pivot so that it can rotate. The compass needle points in the direction of ...

Magnet technology has advanced, year-over-year, pulled by the desire of scientists for ever-higher magnetic fields. But progress has been paced by new developments in properties of materials needed to ...

Magnets and magnetic fields have become increasingly common in modern technical products, appliances, automotive, and industrial products and systems. Factors such as the continuing emphasis on energy ...

Last month, a new superconducting magnet reached its design field of 11.5 Tesla at a temperature nearly as cold as outer space. It is the first successful twin-aperture accelerator magnet made of ...
