Abstract:
A magnetic field structure is provided and includes: two magnetic poles disposed in a magnetic circuit path and opposite to one another to form a space therebetween for receiving an element to be tested; a magnetic field source for providing a magnetic field in the space; and an optical positioning element disposed in one of the two magnetic poles for optically positioning the element to be tested. Therefore, the magnetic field structure can simultaneously provide a strong magnetic field and a precise positioning function.
