Multipole magnet, method of producing, and sensor system comprising same

A method of producing a permanent magnet in the form of a multi-pole magnet having an axis, the multi-pole magnet having a plurality of at least four poles as seen from a point on said axis;

• the method comprising the following steps:
• a) providing a shaped body comprising or consisting of an isotropic magnetic material, the shaped body having an axis and a centre;
• b) providing a number of at least four electrical conductor segments arranged in a plane perpendicular to said axis, the conductor segments being oriented radially with respect to said axis, and being angularly spaced by an angle of 360° divided by said number;
• c) simultaneously applying or inducing or otherwise make currents flow through each of said number of conductor segments, the currents in the even numbered conductor segments flowing towards the axis, the currents in the odd numbered conductor segments flowing away from said axis.
