DC Vacuum Circuit Breakers based arc control has been a major topic in the last few decades. Understanding vacuum arc (VA) gives the ability to improve vacuum circuit breakers capacity. In this paper, the interaction of a DC vacuum arc with a combined Axial-Radial magnetic field was investigated. The proposed system contains an external coil to produce axial magnetic field (AMF) across the vacuum chamber. The vacuum interrupter (VI) contacts were assumed to be untreated radial magnetic field (RMF) contacts. For this purpose, Finite Element Method (FEM) based Multiphysics simulation of the immerging magnetic field influence on the VA is presented. The simulation shown the ability of the presented system to deflect high DC vacuum arc, also reveals that the vacuum arc interruption capability increases with the rise of the axial component of the magnetic field. Simulation results shown that this method can be applied to improve the interruption capability of the VI.

Thermomagnetic convection is still a phenomenon which generates interest among researchers. The authors decided to focus their attention on the magnetic field influence on forced convection and analyze the extended Graetz–Brinkman problem. A numerical model based on a commonly available solver implemented with user-defined functions was used. The results exhibited the variety of possible flow structures depending on the dimensionless parameters, namely Prandtl and Reynolds numbers. Three flow structure classes were distinguished, and they provide a platform for further research.

The geometry structure of the magnetic field in colliding stellar winds is studied. It is shown that the magnetic field influence in the interaction region depends mainly on the ratio of the wind ram pressures of the components, the ratio of the stellar linear rotational velocity to the wind velocity of the magnetized star, and the stellar separation. For the radiative colliding winds the magnetic field influence increases with the importance of the radiative losses. An asymmetric magnetic field structure appears for a given set of binary parameters and the interaction region might be an asymmetric source of non-thermal radio emission.

Based on the X-ray method an experimental research has been carried out aimed to estimate the pulsed magnetic field influence on the heterodiffusion of Al in -Fe within the temperature interval of 700-820 °С and at the amplitude intensity of the magnetic field pulse equal to 0–557.2 kА/m and its frequency ranging from 0 to 8 Hz. It is established that the pulsed magnetic field changes noticeably the value of the measured coefficient of Al diffusion in -Fe. Possible mechanisms of the pulsed magnetic field influence on the diffusion process are considered on taking into account the interaction of moving domain walls, dislocations and impurity atoms.

Results of the experimental study of the long solenoid longitudinal magnetic field influence on stretching of metal shaped-charge jets in the free flight are presented. Shaped charges with a diameter of 50 mm with copper conic liner were used in experiments. Parameters of the solenoid discharge circuit with the capacitive store of energy were such that the characteristic time moments of magnetic induction maximum achievement made about 100 μs. For the magnetic field parameters realized in experiments with the maximum value of an induction up to 10 T the small increase in depth of steel target penetration was recorded which wasn't exceeding 10 %. The possible reasons of big difference of the received results with the results of similar experiments are discussed.
