Summary
The essential task of the working group is the realization and maintenance of the unit Tesla of the magnetic flux density B as the base unit of magnetic quantities. The dissemination of the unit Tesla is realized by: Magnetic measurements basing on nuclear magnetic resonance (NMR), calibration of field coils as standards of DC fields and AC fields, and calibration of magnetometers in DC fields and AC fields. Special tests are done on request, such as: the measurement of field profiles on the coil axis and the characterization of the field in front of the pole tips of permanent reference magnets. One more task of the working group is the characterization of magnetic materials and the development of the equipment needed for these measurements.
