Learn MoreSingle-Axis Helmholtz Coil
Product Description
The Helmholtz coil is a device composed of two sets of identical circular coils placed parallel to the same axis and run current in the same direction to generate a uniform magnetic field. Helmholtz coils can be customized by through adjusting the coil diameter, required magnetic field, working time, structural requirements, and dissipation requirements (air cooling or water cooling). -

Clamp Type Electromagnet
Clamp Electromagnet, of which the shape is like a vice, has two magnetic poles protruding outside the coils. It is usually used to generate an in-plane magnetic field. It is suitable for special operation environments such as microscopy, probe station, the limited space, magneto-optical experiment, and magnetic mineral powder screening. The Clamp Electromagnet is basically custom-made, and can be designed and produced according to user's application conditions and magnetic field requirements.

The static geomagnetic active shielding system
The static magnetic field active shielding system can offset the magnetic field fluctuations of the geomagnetic field in real time, thereby generating a 10nT zero magnetic environment in the geomagnetic environment. For example, the gradient magnetic field of 1nT or 0.1nT can be generated in the shielding room or shielding cylinder, the system can also generate any set magnetic field in three-dimensional components for scientific experiments and simulation of geomagnetic changes.

Three-Axis Equal-Diameter Coil
The Three-Axis Equal-Diameter Coil, which is a type of three-axis Helmholtz coil exclusively developed by our company, features the nominal diameter coil, the same number of winding turns, and the same specification of wires per axis.<br/> This winding construction allows the Three-Axis Equal-Diameter Coil to have the same resistance, inductance, homogeneity, and B/I coefficient per axis; The coil per axis is fixed to each other in the embedded form, of which this mechanical structure makes the coil to feature a small size and the greater accessibility to the working gap; the whole former is made of non-magnetic PMMA material, which is applied for the study of low and weak magnetic field, and which is very suitable for the shielding room and the magnetic shield. The highest magnetic field of a three-axis equal diameter coil can be designed to be from 0 to 5 Gs.

Magnetic-Moment-Free Coil
The Magnetic-Moment-Free Coil is composed of several pairs of coils, which are installed in a certain geometric structure, and of which the certain number of coil’s turns and a certain current direction make the magnetic field outside the Magnetic-Moment-Free Coil attenuate rapidly and make the magnetic moment of the Magnetic-Moment-Free Coil be zero. One of outstanding advantages of the moment-free coil is that it does not produce magnetic interference to the environment outside a certain distance from the Magnetic-Moment-Free coil during operation, which means that it is very significant for the simultaneous operation of multiple systems; In addition, the moment-free coil does not magnetize the adjacent magnetic substance, therefore, it does not bring extra errors to the moment-free coil in this respect.

HALL EFFECT MEASUREMENT SYSTEM
HALL EFFECT MEASUREMENT SYSTEM is used to measure the important parameters of Semiconductor Materials such as Carrier Concentration, Mobility, Resistivity, and Hall Coefficient, and so on. These parameters must be grasped and controlled in advance in order to understand the electrical characteristics of semiconductor materials. Therefore, the Hall Effect Measurement System is an indispensable tool for understanding and studying the electrical characteristics of Semiconductor Devices and Semiconductor Materials. The experimental results are automatically calculated by the software, and the Bulk Carrier Concentration, Sheet Carrier Concentration, Mobility, Resistivity, Hall Coefficient, Magneto-Resistance, and other parameters can be obtained at the same time.
