The paper presents an analytical method for the determination of the magnetic force produced by a mini – actuator with permanent magnets. The results are compared with those obtained by performing a numerical field analysis with COMSOL Multiphysics, showing a very good agreement. The study reveals that the actuator has two equilibrium points, one of which is stable and the other one unstable.

This poster presents analysis and validation of a tri-axial square Helmholtz coils system (see Figure 1), commonly used to generate highly uniform magnetic field on a specific volume. The analysis of square Helmholtz coil is based on the Bio-Savart law [1] for which it performs a Taylor series approximation for the magnetic field at a point on the axis of symmetry, finding an approximate expres...

The development of numerical analysis methods and, first all, the finite element method (FEM), makes it possible to obtain accurate solutions for quite complex objects. Such objects include mobile electric vehicle charging units (MCUs). MCU under will have a rather design, experiencing significant static and dynamic loads in operation, so their reliable calculation is only with help FEM, which ...

In this study, the design and analysis of micro beam is carried out using COMSOL multiphysics. The current passing through distributes heat energy due to its resistance that pushes entire desired distance thermal expansion. This expansion varies depending on amount emitted temperature. purpose model created estimate temperature increase required cause displacement in proposed software. addition...
