Barkhausen

/ ˈbarkhaʊzən /

noun

1. BarkhausenHeinrich Georg18811956MGermanSCIENCE: physicist 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

This avalanche effect was first demonstrated in magnets by the physicist Heinrich Barkhausen in 1919.

From Science Daily

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.

From Science Daily

This is the first time quantum Barkhausen noise has been detected experimentally.

From Science Daily

"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.

From Science Daily

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.
