Abstract
A ferrofluidic electromagnetic power generator installed within a rotating object, such as the interior of a vehicular tire generates electric current in an electrical coil wound about an elongated, hermetically sealed housing made of non-magnetic material, partially filled with magnetized ferrofluid. A permanent magnet and two magnetic pole pieces enclosing the housing and the coil in conjunction with the ferrofluid form a magnetic circuit. Rotation and horizontal velocity of the tire will propel the magnetized ferrofluid within the sealed housing causing induction in the electrical coil.
