A magnetically driven reciprocating power output system including: at lea st one first electromagnet having a direction of elongation defining an axia l direction, having a first end and a second end, and having an elongated op ened core extending from the first end to the second end, the core having an axis of symmetry substantially coaxial with the axial direction; a control unit adapted to provide a first power input to the first electromagnet and a dapted to cause the electromagnet to have a time-varying first magnetic fiel d with a first polarity directed in substantially the axial direction; at le ast one stationary body having a second magnetic field with a second polarit y directed in substantially the axial direction and configured substantially coaxially with the core region at the first end; at least one reciprocating ferromagnetic body configured substantially coaxially with the core, and no t extending completely outside of the core at the second end, adapted to hav e a second magnetic field in response to the first magnetic field, the body displaceable axially in response to the first and second magnetic fields; an d a transducer unit mechanically connected to the reciprocating body and ada pted to convert a displacement of the reciprocating body to a power output.< /SDOAB>
