      Helmholtz coil
      Model:HHS5024-12

      Profile

      The magnetic field strength produced by Helmholtz coil HHS 5024-12 of 20cm semi-diameter can be calculated by current (H = 42.93xI), or use sensor coil of 13.3 cm diameter (36-turn) to measure in the center. Helmholtz coil fully comply with MI-STD-461F RS101 and ISO 11452-8 standard for magnetic field immunity test.
