Barkhausen

/ ˈbarkhaʊzən /

noun

1. Heinrich Georg . 1881–1956, German physicist; discovered that ferromagnetic material in an increasing magnetic field becomes magnetized in discrete jumps (the Barkhausen effect )

Example Sentences

By wrapping a coil around a magnetic material and attaching it to a loudspeaker, he showed that these jumps in magnetism can be heard as a crackling sound, known today as Barkhausen noise.

"Barkhausen noise is the collection of the little magnets flipping in groups," says Christopher Simon, lead author of the paper and a postdoctoral scholar in the lab of Thomas F. Rosenbaum, a professor of physics at Caltech, the president of the Institute, and the Sonja and William Davidow Presidential Chair.

They wrapped a coil around it, applied a magnetic field, and then measured brief jumps in voltage, not unlike what Barkhausen did in 1919 in his more simplified experiment.
