Uniform Electromagnetic Field

As there are relatively fewer studies about non-uniform magnetic field design and numerical analysis, a model of wedge pole electromagnet has designed and analyzed based on the traditional electromagnet design method. The effects of coil turn, conductor sectional and electric current density on magnetic field intensity had also designed and calculated. The design and numerical analysis of wedge pole electromagnet were conducted which adopted the finite element simulation and optimal design method. The magnetic induction intensity for the wedge pole electromagnet in different positions of the air gap had analog calculated. The simulated and test results for distributing magnetic field can be well corresponded by considering the effect of eddy loss, material and machining errors of electromagnetic. The result indicated that the method of simulation is correct and practical. The method provides a reliable simulation analysis and empirical data for the design of non-uniform magnetic field.

External Uniform Magnetic Field

We investigate both numerically and analytically the behavior of a spin-1 antiferromagnetic isotropic Heisenberg chain in an external uniform magnetic field. Extensive DMRG studies of chains up to N = 80 sites extend previous analyses and obtain the zero-temperature correlation functions. We argue that, despite the presence of a magnetic field, the model is still well described by an O(3) nonlinear σ-model. A saddle-point analysis, that also includes Gaussian fluctuations, is developed for the latter both at zero and finite temperatures. Its predictions are compared with those of the numerical analysis and with the existing experimental literature.

The Magnetic Field

Laser-produced plasma cloud evolution in a magnetic field is investigated up to 3 kg using photographs and spectroheliograms. Generation of a plasma jet, oriented across the magnetic field, was detected, whose emission increases with the field strength and is more distinct for multicharged ions. The effects of the field on the interaction of closely located laser-produced plasma clouds were studied as well. The results of numerical analysis comply with experimental data on plasma behavior in the magnetic field.
