In the measurement of magnetic fields by means of Hall probes or measuring coils it is necessary to calibrate the instruments in a known magnetic field. Our standard field coil according to Helmholtz enables the production of a magnetic field calculable with high accuracy from the dimensions and the amperage. In series arrangement with an accurate ammeter field strengths of up to 800A/cm are produced. The field room is accessible both in axial and radial direction.
Helmholtz coils with fluxmeters are also useful in testing of magnets. Helmholtz coils give repeatable results as against the search coils due to which the magnets can be compared with more accuracy for their total flux and in tern their quality.
