Magnetic field detector

€10.75
Tax included

This magnetic field detector consists of a sheet with nickel particles in a gelatinous suspension.
The flux detector will be darker in color when the magnetic field is perpendicular to the foil (for example, near the poles), and it becomes lighter when the magnetic field runs parallel to the foil.
Ideally in order to determine the servo position, or to adjust already built-in servos.
