Abstract
Isothermal convection in ferrofluids has been induced by a gradient in particle concentration antiparallel to a magnetic field gradient. The deviation of local particle concentration from its equilibrium value produced by the convective motion of the whole fluid gives rise to a c orresponding spatial variation of magnetization. This variation has be en observed by magnetic neutron scattering in good agreement with expe ctations based on flow measurements with an anemometric method.
