The 5451 Helmholtz Coil Electromagnet has an aperture diameter of 300 mm (11.8 inch) with an operating range to 54 mTrms (540 Grms). The Helmholtz Coil Electromagnet can be mounted in any orientation and with a mass of 100 kg (220 lbs) the 5451 can be integrated into experimental or test equipment. Since the Helmholtz Coil configuration is not magnetically shielded, magnetic and electrical conducting materials should be kept at least 1 m from the Electromagnet center to avoid excess distortion of the magnetic field within the working volume.

The Hlelmholtz Coil Electromagnet has an aperture diameter of 160 mm (6.3 inch) with an operating range to 3 mTrms (30 Grms) at frequencies from dc to over 3 kHz. To prevent eddy currents during operation the coil support frame is machined from Delrin plastic. High frequency field operation is limited by the coil inductance of about 8 mH and the peak operating voltage of 250 V. The 5452 can be mounted in any orientation and the low mass of 6 kg (13 lbs) facilitates integration into experimental or test equipment. Since the Helmholtz Coil configuration is not magnetically shielded, magnetic and electrical conducting materials should be kept at least 300 mm from the Electromagnet center to avoid excess distortion of the magnetic field within the working volume.

The shielded enclosure allows increased maximum field and limits fringe fields to very low compared to traditional “open” Helmholtz coil.

]]> Bartington Helmholtz Coil System, HCS https://gmw.com/product/helmholtz-coil-system/ Thu, 14 Feb 2019 20:57:21 +0000 https://gmw1.wpenginepowered.com/?post_type=product&p=2637 The HCS Helmholtz Coil System generates a magnetic field of known frequency and intensity from a standard single phase AC mains supply. A mounting table is provided to hold the test item inside the homogeneity colume.

The CU1 Control Unit interfaces with a National Instruments control system, controlling the entire system through LabVIEW based PC software.

Applications

  • Calibration of 3-axis magnetic field sensors
  • Cancellation of magnetic fields
  • Creation of a known magnetic environment
