The origins of magnetic steel can be traced back to the 18 th century when scientists began experimenting with iron alloys. In 1820, Hans Christian Oersted's accidental discovery of electromagnetism ...

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 ...

The number of patients carrying ICDs is ever increasing, so these devices are present in numerous medical circumstances and have to be evaluated by physicians who do not have expert knowledge of all ...

This video explores the nature of magnets and how they create invisible magnetic forces. It explains the origin of magnetism, how magnetic fields are formed, and the role of electrons in generating ...

Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, ...

A new tomography-based approach can reconstruct the real microstructure of ultrafine-grained Nd-Fe-B magnets in large-scale models. Micromagnetic simulations on the tomography-based models reproduced ...

The energy-efficiency regulatory update scheduled for 2023 will affect builders of HVAC equipment, industrial fans, cooling towers and pumps, including those used in irrigation systems. The new ...
