Abstract: The present application relates to a ferrofluid control device, which generates two different magnetic fields by placing the first magnetic conductor and the second magnetic conductor at different positions of the first coil group, thereby enabling the ferrofluid to produce more abundant dancing effects. Furthermore, a richer dancing effect can be realized by adding the second coil group and the third magnetic conductor.
