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). -
Learn MoreThree-Axis Helmholtz Coil
Product Description
The three-axis Helmholtz coil is composed of 3 pairs of Helmholtz coils arranged along three orthogonal axes, which can simultaneously generate uniform magnetic fields in the direction of x-, y-, or z-axis.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).

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.

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.

WDS Series Electromagnet
The WDS electromagnet is a C-Frame, variable air gap magnetic field generation equipment with each pole being adjustable. From the excitation of the excitating power source, the field vector forms a closed loop, and a high uniform magnetic field can be generated between two poles, and the field direction is along the axial direction of pole caps. All WD electromagnets are equipped with a pair of standard replaceable pole caps made of purity iron, which can be replaced to suit to individual experiment requirements. The pure-iron structure is suitable for coils heat dissipation, and the option of cooling water system is also available for extend the operating time.

High Homogeneity coil
High Homogeneity coil, which is composed of multi-ring coils arranged along the axial direction, includes the common coils such as Barker Coil, Braunbek Coil, Maxwell Coil, Rubens Coil, and Magnetic-Moment-Free coil. Compared with the Helmholtz coil, the combined coil features the better magnetic field homogeneity under the same diameter, the higher homogeneity and larger homogeneity volume in the effective space, and is suitable for the high-precision and large-range magnetic field needs. This design can meet any parameter customization requirements.
