For measuring magnetic flux density of small fields in the axial direction with CASSY (
524 013,
524 006,
524 005W2,
524 018) or universal physics measuring instrument (
531 835). For example, useful in measuring the earth's magnetic field (40 ... 60 µT) or for measuring a field surrounding a current-carrying conductor for direct and alternating currents (Biot-Savart). Including a nonmagnetic stand rod with thread.
