A property by this name is a plasma figure of merit proportional to the volume integral of the pressure divided by the flux density. A substance's propensity to undergo this phenomenon is calculated as the sum of the mean square radii of electron orbits times the square of electron charge divided by six times electron mass times the number density. That value is always negative, typically has a magnitude around ten to the minus sixth, and is known as the susceptibility.

That value is always negative, typically has a magnitude around ten to the minus sixth, and is known as the susceptibility. Outside of superconductors, it is most visible in substances with symmetric electronic structure and no permanent magnetic moment. It is an effect of changes in electron orbital velocity as predicted by Lenz's law. For ten points, name this type of magnetism which can be induced in opposition to the external field in any substance.
