The Magnetic Field

A circuit breaking electromagnetic system is the actuator and digital controller for a switching device. Its performance can significantly affect operations of the switching device. We propose a dynamic simulation method coupling the electric field and the magnetic field for the circuit breaking electromagnetic system and its drive circuit. The method combines both statistic and dynamic analyses, and differential equations. Finally, we utilize the flux transformer as an example to validate this method and reveal the dynamic characteristics of the drive transformer by changing the parameters of the drive circuit.

This research was conducted as an alternative learning for the study of the magnetic field using the 2D Ising Model with simulation method. The programs are written in macro language and ran in ImageJ software. The research of designing a system size namely 32 x 32, energy and magnetization are measured as functions of temperature. Simulation conducted to see the magnetic momen when temprature is changed on the system. It is found that for low temperature regime, the absolute magnetization close to 1, which means tha tall spins are in the homogeneous state. By the increase the temperature close to the critical one = 2,3, the magnetization decrease drastically into zero. For the energy, low temperature regime gives the low energy. By the increase the temperature, the energy increase drastically near the critical temperature, and finally close to zero for high temperature regime. The state of the system is changed from ferromagnetic into the paramagnetic.Keywords : Magnetic Field, Magnetization, Energy, 2D Ising Model, Learning.

Abstract Studies of the dynamics of a round submerged jet of liquid metal in a transverse magnetic field. The experiments were performed in the range of Reynolds numbers up to 1000 and Hartmann numbers up to 1300 using a probe technique for measuring velocity using potential sensors. Detailed three-dimensional flow structures are visualized using a direct numerical simulation method independent of the experiment. The paper presents data on the averaged velocity field and statistical characteristics of the flow, reproducing the complex nature of a substantially unsteady flow, in which zones of reverse fluid flows are detected and a significant heterogeneity of the velocity field is observed.
