Abstract: FIELD: electricity. 
     SUBSTANCE: within a certain special interval L one creates a saturating magnetic field for the ferromagnetic substance that is moved within the said special interval at a certain speed V the value whereof is coordinated with the ferromagnetic substance magnetic viscosity relaxation timing constant τ; this results in production of mechanical energy in the form of an additionally occurring power impulse applied to the ferromagnetic substance from the part of the saturating magnetic field; the ferromagnetic substance is preliminarily magnetised in a direction longitudinal in relation to that of the ferromagnetic substance movement within the magnetic field for magnetic response maximisation; then the ferromagnetic substance is introduced into the magnetic gap localised within a space length whereof amount to L; the gap is composed of two skew-magnetised parallelepipeds the analogous magnetic poles whereof are turned to each other, the tilt of the skew-magnetised parallelepipeds magnetisation vectors selected as matching that of the vector of speed of the ferromagnetic substance drawing through the said magnetic gap; one additionally ensures inflow of thermal energy from the environment to the ferromagnetic substance which compensates for the ferromagnetic substance internal thermal energy during demagnetisation in the process of magnetocaloric effect. Additionally proposed is a device implementing this energy production method; the device contains a working permanent magnet and a ferromagnetic substance interacting with the latter and shaped in the form of a disc (ring) with radius R connected with the rotation axis; the edge of the disc (ring) is placed into the saturating magnetic field of the working permanent magnet localised within a with length amounting to L tangentially to the disc (ring); before the working permanent magnet an additional cylindrical magnet is introduced wherein the edge of the ferromagnetic disc (ring) is placed with the working permanent magnet positioned immediately after it along the rotation; the working permanent magnet consists of two skew-magnetised parallelepipeds the magnetisation vectors whereof are tilted in the direction of the ferromagnetic disc (ring) movement through the resultant gap with length L; the said two skew-magnetised parallelepipeds have their analogous magnetic poles are turned to each other; the ferromagnetic substance magnetic viscosity relaxation constant τ and the angular speed of rotation of the disc (ring) with radius R ω 0  are selected from the condition ω 0 =0.82R/τR where ω 0  determines the maximum rotation momentum occurring in the ferromagnetic disc (ring) with the intensity of the saturating magnetic field in he working permanent magnet selected to be at least a sequence higher than that of the longitudinal magnetic field in the additional cylindrical magnet. Adoption of the proposed technical solution will create in future conditions for production of environmentally safe energy that will not serve to aggravate the global warming problem and will enable usage of traditional fuel resources (oil and gas) for other more efficient purpose, such as - for creation of new materials in chemical industry. 
     EFFECT: improved energy efficiency of environmental thermal energy conversion into mechanical work.
