The Schwarzbeck HHS 5210-100 2.5 Square Helmholtz Coils are expertly designed to generate precise magnetic fields over a frequency range from DC to 10 kHz. Each coil features 100 turns and can handle a maximum coil current of 20 A for 5 minutes, achieving a maximum magnetic field strength of 2900 A/m at a 0.4 m coil distance. With an inner side length of 1.0 m and a maximum coil separation of 0.70 m, these coils offer flexibility for various testing and calibration setups. The inductance per coil is 31.3 mH, and the pair has a resonance frequency greater than 25 kHz, ensuring high performance and stability. Optimized for best uniformity at a 0.566 m coil distance, the magnetic field strength per 1 A coil current is 124.66 A/m. These coils are ideal for precise magnetic field calibration and immunity testing, providing exceptional accuracy and reliability.
