On the Variation of Resistance in a Steady Magnetic Field observed in Nickel, Antimony, and Tellurium Plates

Extract

Whether the variation of resistance in conductors in a steady magnetic field depends on the field strength, on the magnetisation, or on both, does not seem to be definitely settled. The various experimental methods as yet used are fundamentally similar in principle, and have the disadvantage that the experiments are difficult to perform.

A method where the experimental difficulties are very few is to be found in the comparison of the variation of resistance for any given field-strength with some other phenomenon whose dependence on the field-strength or on the magnetisation is already known, and whose exact determination offers no experimental difficulties.
