Tri-Axial Square Helmholtz Coils System to Generate Uniform Magnetic Field Volume
Published in 2014
The study of the effects of magnetic field stimulation in biological systems require devices capable of generating homogenous magnetic fields and further guarantee a controlled and repeatable exposure to different samples involved in the experiment [1]. This work presents analysis and validation of a tri-axial Square Helmholtz Coils (SHC) system, commonly used to generate highly uniform magnetic field on a specific volume. The analysis of SHC is based on the Bio-Savart law [3]. In order to verify the distribution and uniformity of each component of the magnetic field Bz, By and Bx on workloads, a 3D computational model was designed in COMSOL Multiphysics® software.
