    Aug 27, 2019 · For the 39 K Helmholtz coil, one cable trap tuned to f 1H, was used (λ 39K ≈ 22 m). The size of the 39 K loop elements was chosen to provide acceptable signal uniformity in the region of interest (ROI), sufficient coverage of the heart and to minimize coupling with the 39 K coil.

    The Helmholtz cage control station is equipped with a three-axis digital to analog converter (D/A). Each D/A channel is connected to a power amplifier that provides current to the coils based on the analog input received by the D/A. To compensate for the uncertainties in the coils model, a feedback control is implemented inside the Simulink ...

    For the probe calibration, simple Helmholtz coils were used. Their field uniformity in the central part that was obtained by the numeric integration can be seen in Fig. 2, which shows main and parasitic components. The parameter is the distance from coil axis. The rectangle shows area where the deviation is less than 1 %.

    3. Spherical coil with variable winding 4. Helmholtz coil Helmholtz coil in the above cases, have the most of applications in EMC tests. Helmholtz coil is constructed with either circular or square coils. The field generates is the sum of the fields generated by the two spaced coils [7]. III. SIMULATION STRUCTURE The Helmholtz coils were constructed in accordance with the guide- lines in the ASTM 698-74 standard. They were fabricated from ¾/4-in. plywood, 1/2-in. Extren® threaded rod, and 14 AWG copper (coated) wire. Each coil had a diameter of approximately 47.5 in. (1.219 in), with 48 turns each of the copper wire.
