About Flux quanta
The magnetic flux quantum (Φ₀ = h/2e) equals exactly 2.067833848×10⁻¹⁵ Wb (2019 SI definition). The natural unit of flux in superconductors - flux enters a type-II superconductor in integer multiples of Φ₀ (Abrikosov vortices). Used in SQUID, Josephson junction and quantum computing metrology. 1 Φ₀ ≈ 2.068 fWb.
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.
