One variety of this pheno
One variety of this phenomenon can be generalized with octonions, using an explicit solution of the Hopf map. It is predicted to cause large-scale EMF quenching in galaxies and stars involved in mean-filed dynamo theories. In another phenomenon with this name, opposite spins accumulate in spirals inside of  a wire; that phenomenon was theorized by Dyakonov and Perel. The stationary plasma thruster, which uses xenon ions to generate impulse, is a propulsion device that utilizes this effect. Another version of it produces particle paths shaped like logarithmic spirals and is called the Corbino effect.  One variant of it in two dimensions defined as Planck's constant divided an integer times the charge of an electron squared as a quantized unit of resistance. That quantum variety was discovered by Klaus von Klitzing. For 10 points, name this effect  in which a transverse force is exerted on charge carriers under the influence of a magnetic field.

Hall Effect (accept quantum Hall effect or quantized Hall effect before "large-scale EMF quenching")
