Magnetic Module 6'000 A/m (75 Gauss)

This magnetic field generator has been developed with the aim of studying and testing movements and watches in accordance with NIHS 90-10 standards (ISO 764:2002).

Precision and innovation in Helmholtz coil design

Inspired by the pioneering physicist Hermann von Helmholtz, our Helmholtz coil design embodies precision and innovation. Constructed from two meticulously engineered copper coils, each with a precisely defined radius, these coils are positioned at a distance equal to their radius. This clever arrangement leads to a notable outcome – the central convergence of magnetic uniformity, forming a focal point of exceptional precision.

Due to the inherently three-dimensional nature of magnetic field perturbations, our approach involves the incorporation of rotational capabilities for both the coils and the watch holder. This thoughtfully engineered design enables a thorough exploration of the impact of magnetic fields from a multitude of angles and perspectives, offering a comprehensive understanding of their effects.
