a simple new closed form of the green function for axisymmetric magnetostatic problemsis found analytically in cylindrical coordinates. the result is verified by applying several examples.

Three different approaches to calculating the forces acting on ferromagnets in a stationary magnetic field are considered. The results of by these methods test model compared with measurement data obtained using an experimental unit. Keywords: numerical simulation, magnetostatics, calculation force, Maxwell tensor.

For several years, biologists have used superparamagnetic beads to facilitate biological separations. More recently, researchers have adopted this approach in microfluidic devices [1-3]. This recent development and use of superparamagnetic particles in biomedical and biological applications have resulted in a necessity for methods that enable the understanding and prediction of their properties...

Partial differential equations and variational problems can be solved with physics informed neural networks (PINNs). The unknown field is approximated networks. Minimizing the residuals of static Maxwell equation at collocation points or magnetostatic energy, weights network are adjusted so that solution approximates magnetic vector potential. This way, flux density for a given magnetization di...
