The paper presents the micro/nanoscopic model of a material inserted in a magnetic field. The model accepts the time component of an electromagnetic field from the perspective of relative motion of systems. The relatively moving systems were derived and tested, and the influence of the motion on the superposed electromagnetic field was proved to exist already at relative motion speeds in the order of units of ms-1. In micro- and nanoscopic objects such as biological tissues, the effect of an external magnetic field on the growth and behaviour of the biological system needs to be evaluated. We designed the model based on a description using Maxwell equations of the electromagnetic field, and we also extended the monitored quantities to include the various flux densities; moreover, the time flux density was monitored as a quantity. This quantity was then experimentally examined on the physical problem of the speed of heating a defined volume of a homogeneous material in relation to the magnitude and type of the surrounding magnetic field. Experiments were conducted with growth properties of simple biological samples in pre-set external magnetic fields.
