DXCG type electromagnet, also known as magneto-electromagnet, it is based on the structure of the electromagnet fully consider the optical path and the magnetic field and the sample angle, in a limited space to achieve the largest magnetic field. CG-type magneto-electromagnets are suitable for Farady transmissive and Kerr-reflective magneto-optical effects, as well as Smoke experiments and other magneto-optical experiments. Vertical magnetic field and horizontal magnetic field, or the application of rotating magnetic field requirements can be achieved. Some of the probe platform, microscope under the objective of the magnetic field design, can also be classified as such magnets.
DXCG-type magneto-electromagnet can be made into SB, SBV, WD, SG, shaped and other forms, the direction of the magnetic field can be parallel to the ground can also be perpendicular to the ground, adjustable air gap, single yoke can be selected according to the direction of light. Farady effect electromagnet pole axis open conical hole, cone angle 2 ~ 14 °, pole center hole for Φ2 ~ 3mm, pole can also be replaced, can take into account the Kerr effect test. It is characterized by easy loading and unloading samples, magnetic field air gap can also be adjusted for repeated measurements. Users can customize the special specifications of the electromagnet according to the required magnetic field space and magnetic field strength.
