Device
Working principal
Named after the physicist Hermann von Helmholtz, the Helmholtz coils design consists of two copper coils of defined radius separating by a distance equal to this radius. This design maximizes the uniformity of the field at the center of the coils and cancels out the Earth’s magnetic field.
Rotational
Because the perturbations caused by magnetic fields are highly three-dimensional, both the coils and the watch holder are rotational. The impact of the magnetic field can thus be studied from all angles.
