5H30.50 - Magnetohydrodynamic Motor - Ion Motor
The MHD motor is designed to run on the overhead projector. Hook the power supply to the electrodes as shown. Remember that there is a magnet that the center electrode fits over. Fill the dish with sat'd copper sulfate sol'n until it is even with the top of the outer electrode. Turn on the power and watch the liquid rotate about the center electrode. Reverse the power supply leads and the liquid will rotate in the opposite direction. Sprinkle some Lycopodium powder on the top of the copper sulfate to make the rotation highly visible.
