Invalidation of the Kelvin force in ferrofluids.
Direct and unambiguous experimental evidence for the magnetic force density being of the form MnablaB in a certain geometry-rather than being the Kelvin force MnablaH--is provided for the first time. ( M is the magnetization, H is the field, and B is the flux density.)
