Appearance of Magnetism 3
Experiment of Shape using magnetic fluid

This piece is composed of two electro magnets, a responsive timer relay, power source, and magnetic fluid. Magnetic fluid is put into the center plate, and the two electro magnets are placed above and below it so that the same polar sides are facing each other. The eletro magnets are controlled individually to increase or decrease magnetic strength. The magnetic fluid can change shape within the magnetic field created by the two electro magnets.
