How Many Combinations Can You Create with One Set of Helmholtz Coils?

Breaking Traditional Limits, Defining the Next-Generation Magnetic Field Solution

In fields such as materials research and biomagnetism, a stable magnetic field environment is the cornerstone of experimental success. Our 60-90mT large-bore solenoid addresses three core pain points with technological innovation.

Building a 'Zero-Magnetic' Space for SERF Atomic Magnetometers

Research on magnetocardiography and magnetoencephalography functional imaging at a quantum precision measurement laboratory in a top 985 university. The team independently developed a spin-exchange relaxation-free (SERF) atomic magnetometer with sensitivity reaching 10 fT/√Hz. However, geomagnetic field disturbances (~50 μT) and laboratory stray magnetic fields cause frequent depolarization of atomic spins, resulting in a signal loss rate of up to 40%, and weak magnetic anomaly signals are submerged in noise.

University Case | Φ150mm Water-Cooled Horizontal Electromagnet

The head of a magnetoelectric functional materials team at a Double First-Class university stated: "Our chiral magnetic domain observation project requires a uniform magnetic field environment that can accommodate a complex optical path system, with temperature fluctuations less than ±0.5°C during 72 hours of continuous operation. After surveying the market, we found that either the magnet volume was insufficient or the thermal stability could not meet the requirements." The industry's "space-strength-stability" impossible triangle has found its solution in our delivered Φ150mm water-cooled horizontal electromagnet.

Customized Magnetic Field Generation Devices

We provide various magnetic field generation devices including solenoids, Helmholtz coils, electromagnets, custom-shaped coils, and custom-shaped electromagnets, as well as superconducting magnets for ultra-high magnetic field requirements.
