Abstract

A device for generating and controlling a magnetic field strength and a method for generating and controlling a magnetic field strength are disclosed. The generation is very stable and precise. Preferably, reference values of physical variable can be generated relatively simply and economically. In addition, magnetic flux densities can be measured with high resolution and, in particular, highly robustly. The device and the method can also be used for transmitting information, in particular for ultra-wide band communication. The required devices can be very small, in particular miniature, and mobile.

Dependent claims

A device for generating and controlling a magnetic field strength, comprising:

a first material that generates a luminescence and/or a photocurrent upon a physical excitation, wherein the luminescence and/or photocurrent has an extreme value with respect to a magnetic field at at least one magnetic flux density;
means for generating the physical excitation;
means for magnetic field generation, wherein the first material is exposed to the generated magnetic field, wherein the magnetic field strength is adjustable;
means for measuring the luminescence or the photocurrent with a detection signal that represents a strength of a detected luminescence signal or photocurrent signal;
means for control, which are adapted to output a control signal for controlling the means for magnetic field generation and to control the magnetic field strength as a function of the detection signal, such that the detection signal assumes and maintains an extreme value.
