About Microwebers

The microweber (µWb) equals 10⁻⁶ Wb = 100 Mx. Used in small inductor and reed switch characterisation; a ferrite bead on a PCB trace links a few µWb at normal operating flux densities. 1 µWb = 10⁻⁶ Wb = 100 Mx.

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.
