Femtoweber

One femtoweber is equal to one quadrillionth of a weber (1e-15 webers).

History: Femtoweber values appear in sensitive magnetic sensing and small-area flux calculations.

Current use: Used for SQUID-adjacent sensing, microdevices, magnetometry, and trace-flux references.

Also written as fWb.

Weber

Weber measures magnetic flux, defined as the amount of flux that, linking a circuit of one turn, would produce in it an electromotive force of one volt if it were reduced to zero at a uniform rate in one second.

History: Named after the German physicist Wilhelm Eduard Weber.

Current use: Used in electromagnetism, transformer design, and magnetic circuit analysis.

Also written as Wb.
