Abstract
A magnetic structure for an electromagnetic resonator is provided. The magnetic structure comprises at least a solenoid and a permanent magnet, wherein the solenoid and the permanent magnet are concentrically arranged to each other such that the magnetic field lines provided by the permanent magnet are at least essentially perpendicular to magnetic field lines of a magnetic field generated by the solenoid. The arrangement of the permanent magnet and the solenoid may be housed by an element with a high magnetic permeability.

A magnetic structure for an electromagnetic resonator, the magnetic structure comprising:
- a housing element having a high magnetic permeability;
- a solenoid;
- and
- a first permanent magnet;
- wherein the solenoid and the first permanent magnet are housed in the housing element and the solenoid and the first permanent magnet are arranged concentrically to each other with respect to a predetermined axis;
