Inducing a quantized resistivity in the quantum Hall effect, it is expelled from superconductors in the Meissner effect.
When this is strong and temperature is low, electrons in the conduction band behave as oscillators and thus conductivity is quantized in the Shubnikov-van Alphen effect. Using the Josephson effect, a SQUID can detect this to high precision, and it can cause the separation of (*) Landau levels, in addition to causing hysteresis, in some metals. Inducing a quantized resistivity in the quantum Hall effect, it is expelled from superconductors in the Meissner effect. Resulting in a split in p orbital energies of hydrogen in the Zeeman effect, for 10 points, name this type of field whose divergence is zero according to Gauss's law for it, thereby disproving the notion of its monopoles.
