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 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
