Purdue University scientists have uncovered an unusual material that could lead to non-metallic magnets, which might be lighter, cheaper and easier to fabricate than magnets made of metal. WEST ...
Researchers have shown that certain metal-organic materials can act as permanent magnets at temperatures of up to 242 °C, while remaining magnetized in external magnetic fields as strong as 7500 ...
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 ...
