The Schwarzbeck HHS 5213-100 – Square Helmholtz Coils are designed to generate highly precise magnetic fields, ideal for applications from DC to 5 kHz. With 100 turns per coil, these coils provide a strong linear relationship between coil current and field strength, ensuring exact field strength calculations. Capable of handling a maximum coil current of 15 A for short durations and 9 A continuously, these coils deliver a nominal magnetic field strength of 900.9 A/m.
These coils are recognized as a primary standard due to their easily calculable relation between current and field strength, making calibration traceable to current measurements. The Schwarzbeck HHS 5213-100 features a usable frequency range extending to 5 kHz, a maximum coil separation of 0.83 meters, and compact dimensions of 1.46 m x 1.36 m x 0.91 m. With a pair of coils inductance of 88.3 mH and a resonance frequency above 13 kHz, this unit is a robust and reliable choice for precise magnetic field applications.
