The 3D Helmholtz coil allows magnetic fields to be generated in 3 directions (x,y,z). For example, when gauging magnetic sensors, these can be mounted on a holder which is then inserted into a cylindrical coil.
The cylindrical coil, located between two coils in Helmholtz configuration, is responsible for the magnetic field in z-direction. The Helmholtz coil is rotatable and thus provides the x-y component of the field.
A stepper motor is used to rotate the Helmholtz coil. The power supplies for the coils can be controlled via a digital interface thus allowing for predefined measurement profiles.
Magnetic field strength: ca. 30 kA/m max. angle of rotation: ca. 340°
