Barkhausen effect,Weiss domains

 Product No: P0613800
When a sample of iron or nickel is gradually magnetised, the stronger magnetism is not assumed throughout the volume of the metal all at once. Specific areas (Weiss domains) spontaneously change alignments at various times. Every time an alignment changes, a voltage is induced, which can be detected using a loudspeaker or an oscilloscope.
