Kapitsa's Law

an empirical law that established the dependence of the electric resistance of polycrystalline metal objects in strong magnetic fields on the magnetic field intensity. According to Kapitsa’s law, the electric resistance of polycrystalline samples of metals in a strong magnetic field increases proportionally to the magnetic field intensity. The law was discovered by P. L. Kapitsa in 1928 in pulsed magnetic fields with an intensity of up to 350, 000 oersteds. Kapitsa’s law has been established most clearly for copper, gold, and silver.
