Modelling cylindrical permanent magnets with radial magnetization using Comsol Multiphysics

This tutorial demonstrates how a permanent magnet with a cylindrical shape and radial magnetization can be modelled in Comsol by defining a cylindrical coordinate system. The video shows an example of an array of 8 magnets that is used in some types of DC motors. The "magnetic fields, no currents" interface is used to reduce the model size. You can also use the "magnetic fields" interface. 00:00 Introduction 00:44 Geometry 03:54 Coordinate system 05:14 Explicit selections 06:45 Materials 07:42 Physics 09:16 Mesh 11:04 Study 11:48 Results Please subscribe and feel free to ask questions!
