Micropolar continuous medium theory from the beginning was modeling theory. It predicted in that medium existing of mass angular momentum, asymmetrical stress forces, stress moments and mass force momentum. On the beginning there was no able to interpret angular momentum, stress moments and mass force momentum on physical matter known base. In 70’s of XX age there were provided an examples for ferromagnetic, paramagnetic and dielectric bodies. This paper gives attention to interpret those effects in biological structures. On example of human blood there is showed application of Langevin’s paramagnetism classical theory and its mechanical results. In the paper there are presented interesting examples of biological structures which had mechanical results using electric dipole moments.

The trial of the mechanic’s description of material point with variable mass where the classical position vector was replaced with the static moment vector was presented. In this way, the present position and the current mass were bound into a single quantity. The description contains: the dynamic motion formulae, the momentum and the impulse of force, work, kinetic energy, the equivalence of the work and of the kinetic energy as well as the conservation law of mechanical energy. The example of the fall of the evaporating drop in the gravitational field was shown.

Przedstawiona została próba opisu mechaniki punktu materialnego o zmiennej masie w której zastąpiono klasyczny wektor położenia wektorem momentu statycznego. W ten sposób połączono w jednej wielkości aktualne położenie z aktualną masą. W tym opisie przedstawiono : dynamiczne równania ruchu, pęd i popęd, pracę, energię kinetyczną, równoważność pracy i energii kinetycznej oraz zasadę zachowania energii mechanicznej. Przedstawiono przykład spadku kropli parującej w polu siły ciężkości.

In mechanics of continuous media, one of the sub areas is the coupled field theory describing interactions of mechanical, thermal, diffusion and electromagnetic field. All this physical fields are represented in the tensors introduced in this theory. Taking into consideration the momentum and angular momentum of the electromagnetic field in medium requires introduction of the fields: couple stress, mass angular momentum and mass couple in balance equations. From the vectorial nature of momentum, angular momentum, force and couple it appears that the stress tensor and couple stress tensor are the second order. Bearing in mind the importance for modern technology of the physical properties of the surface and surface layer of a solid, the conception of balance equations will be applied to describe the material surface interacting with an electromagnetic field.

Toupin’s version of Saint-Venant’s principle in linear elasticity is generalized to the case of linear magnetoelasticity. That is, it is shown that, for a straight prismatic bar made a linear magnetoelastic material end loaded by a self-equilibrated system at one end only, the internal energy stored in the portion of the bar which is beyond a distance s from the loaded end decreases exponentially with the distance s.
