Magnets can move metal objects without even making contact—but how do they do that? In this video, you’ll learn how magnetic fields are formed, how poles attract and repel, and where we see this ...

Scientists have confirmed the existence of altermagnetism, a third fundamental form of magnetism that could revolutionize ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds ...
