A Method on Decreasing Magnetic Moment of Halbach Cylinder Magnets

Halbach cylinder magnet has been widely used as field source due to its great features. However, the existence of the magnetic moment in the Halbach cylinder magnet limits its application in some fields. To eliminate the dipole moment of the whole magnet system, a method is presented here that incor...

Description
Summary:Halbach cylinder magnet has been widely used as field source due to its great features. However, the existence of the magnetic moment in the Halbach cylinder magnet limits its application in some fields. To eliminate the dipole moment of the whole magnet system, a method is presented here that incorporates permanent magnets to provide an opposite dipole moment. Both the FEM simulation and the experimental results demonstrate that this method is effective.
