Pitt Engineers Explore Next-Generation Electric Motor Technology
Traditionally, electric traction motors use permanent magnets made with rare-earth metals. However, materials such as dysprosium and neodymium are a limited resource. In addition to
How Electromagnets Work
What do a wrecking yard, a rock concert and your front door have in common? They each use electromagnets, devices that create a magnetic field
The Pros and Cons of Using Neodymium Magnets
Neodymium. Its name already sounds exciting. It’s new. It’s dynamic. Together with iron and boron, it forms the alloy Nd2Fe14B, quite possibly the most powerful
Lifting magnets, power sources and electrical control systems
Some magnets are simple, like the small, hand-held versions that hold paper clips or which affix photos, calendars and notes to metal. Magnets attached to
Permanent lifting magnets are safe, fast and efficient
Permanent lifting magnets are powerful magnetic devices that can load and unload burn tables and, when properly installed and operated, provide greater safety than many
Rare Earths Market Forecast: Top Trends That Will Affect Rare Earths in 2023
Rare earths are key elements, and demand for this group of critical metals is expected to be strong in the coming decades as governments around
Magnetism
Magnetism is an invisible force or field caused by the unique properties of certain materials. In most objects, electrons spin in different, random directions. This
Electromagnetism and Electric Motors
Electromagnetism The word “electromagnetism” in physics is used to describe one of the fundamental forces of nature. This force is between subatomic particles such as
Does magnetism decay over time?
My horseshoe magnet isn’t as strong as it once was. Does magnetism decay over time, like radioactivity? Charlotte Ward, Associate professor of physics, Emerita, Auburn
How Electric Motors Work
Electric motors are everywhere! In your house, almost every mechanical movement that you see around you is caused by an AC (alternating current) or DC
