FIELD: physics.
SUBSTANCE: disclosed is a magnetic field generator, having a first and a second set of permanent magnets held together and arranged to form Halbach structures which generate a magnetic field localised in the working hole. These sets form the working region of the generator which is surrounded by said magnets, and at least one of said magnets can rotate around the working region. Based on such a generator, magnetocaloric, magnetooptic, magnetoacoustic and magnetoelectric measuring systems are formed, which enable to conduct analysis in a magnetic field of the order of 1 T and characterised by the possibility of adjusting the value of the magnetic field, as well as compactness of the system and low power consumption.
EFFECT: ensuring smooth adjustment of the value of the generated magnetic field while maintaining high uniformity of the magnetic field.
