Magnets' Noisy Secrets

Have you ever heard of magnets making noise? It's called the Barkhausen effect and it's a name given to the noise in the magnetic output of a ferromagnet when the magnetizing force applied to it is changed.It's easy for scientists to measure the minute thermal fluctuations in ... [ read more >> ]
