  • Magnetic fluid power generator device and method for generating power
    Patent number: 6982501
    Abstract: A device for generating power includes a fluid including magnetic particles. A source magnetizes the fluid thereby inducing rotations in the magnetic particles for creating a magnetic flux. The rotations of the magnetic particles induce an electromagnetic force in a coil associated with the fluid.
