Simple type (up to 1000 Gauss): The coil is directly placed horizontally below the chuck, like a typical probe station.

Advanced version (up to 2 Tesla/2000 Gauss): A pair of high-intensity magnetic field coils are configured to slide on a left and right track. When loading the object to be tested, the magnetic field must be moved away first, and the object must be adsorbed on the chuck while flipping vertically. The probe is placed in the appropriate position through the microscope field of view, and then the high-intensity coil is clamped in the direction of the chuck. After confirming the current magnetic field size with a Gauss meter, electrical signal measurement can begin.
