Convert Maxwells to Femtowebers
Convert Maxwells (Mx) to Femtowebers (fWb) instantly and accurately.
Conversion Formula
fWb = Mx × 10000000
About Maxwells
The maxwell (Mx) equals exactly 10⁻⁸ Wb, the CGS unit of magnetic flux named after James Clerk Maxwell. Still widely used in permanent magnet and motor design datasheets; a typical 10 mm NdFeB disc magnet has a remanent flux of around 10 000-100 000 Mx. 1 Mx = 10⁻⁸ Wb.
About Femtowebers
The femtoweber (fWb) equals 10⁻¹⁵ Wb. Used in SQUID magnetometer research to express flux noise spectral density; a typical high-T₂ SQUID has white flux noise of a few µΦ₀/√Hz, corresponding to sub-fWb/√Hz levels. 1 fWb = 10⁻¹⁵ Wb.
