Abstract: Fluid mixing apparatus includes a non-magnetic conduit (4) and a magnetically susceptible rod (5) which is contained in and extends longitudinally of the conduit. The rod is substantially not permanently magnetized. A least two electromagnets (6, 7) are positioned externally of the conduit so that each may, when activated, individually cause movement of the rod across the conduit. The electromagnets may be activated in turn and one at a time to induce an effective vibratory mixing motion of the rod within the conduit.
