    • Abstract


      The report elaborates, for the first time, visual observations of induced convection in a non-conducting diamagnetic fluid (water) under the action of static magnetic field gradient in the absence of thermal gradients. The convections were induced at room temperature in a suspension of deionised (DI) water and lycopodium pollen grains. The suspension was exposed to a static magnetic field gradient having a magnetic induction strength of 0.12T. Upon application of various configurations of magnetic field gradient over the suspension, different convective flow patterns were observed in the suspension. The results showthat diamagnetic interactions of water are detectable even though its value of magnetic susceptibility is small.
