Modelling and Analysis of Magnetic Field Distribution Generated by a Magnetised Paraboloid

Permanent magnets have a unique ability to generate a permanent magnetic field that has been found in various applications. In this study, to facilitate the design and optimization processes of magnetic devices, fast-computed expressions of the magnetic field created by a magnetised paraboloid are developed. It is demonstrated that the derived models are in good agreement with the conventional Finite Element Analysis (FEA). Moreover, these models are multiple magnitudes faster than the FEA in terms of computational time. Furthermore, analysing the magnetic field distribution generated by this magnet, it is shown that the field is concentrated around its revolute axis....

Permanent magnets have a unique ability to generate a permanent magnetic field that has been found in various applications. In this study, to facilitate the design and optimization processes of magnetic devices, fast-computed expressions of the magnetic field created by a magnetised paraboloid are developed. It is demonstrated that the derived models are in good agreement with the conventional Finite Element Analysis (FEA). Moreover, these models are multiple magnitudes faster than the FEA in terms of computational time. Furthermore, analysing the magnetic field distribution generated by this magnet, it is shown that the field is concentrated around its revolute axis. In addition, the field is sharply concentrated and pointy, close to the apex of the paraboloid. The field expressions and their properties are expected to assist in the design and optimization processes of magnetic devices utilizing this magnet, such as in static magnetic field brain stimulation.
