in 1889 because of his political views, and came to America to continue his engineering
work on transformers and electric power distribution. Unsettled at the inability
to calculate losses due to magnetism in transformers and other AC apparatus, Steinmetz
worked out a theoretical and experimental method for doing so. His result was the
discovery of "hysterisis" properties, the phenomenon by which a material's magnetism
in a given magnetic field can have two different values. The principle has subsequently
been applied to positive feedback in the electrical and mechanical realms as well
as in biology and many other fields. |
