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.

About Webers

The weber (Wb) is the SI coherent unit of magnetic flux, defined as 1 V·s. A change of 1 Wb per second through a single-turn coil induces an EMF of 1 V. Power transformer cores at 50/60 Hz operate at 0.5-1.5 Wb in large units; a generator stator coil links a few Wb per pole. 1 Wb = 1 V·s = 10⁸ Mx.
