Page "Barkhausen effect" Paragraph 4
from
Wikipedia
A coil of wire wound on the ferromagnetic material can demonstrate the sudden, discontinuous jumps in magnetization.
The sudden transitions in the magnetization of the material produce current pulses in the coil.
These can be amplified to produce a series of clicks in a loudspeaker.
This sounds as crackle, complete with skewed pulses which sounds like candy being unwrapped, Rice Krispies, or a pine log fire.
Hence the name Barkhausen noise.
Similar effects can be observed by applying only mechanical stresses ( e. g. bending ) to the material placed in the detecting coil.
