The permanent magnet can be made into a rotating magnetic field in the form of mechanical rotation. When the permanent magnet rotates around the center of action of the magnetic field, the sine wave magnetic field can be obtained in the fixed direction of the magnetic field space. The alternating frequency of magnetic field polarity is 0-7hz adjustable, the magnetic field space is large, and the magnetic field strength can be customized.
Nuclear magnetic resonance (NMR) series permanent magnets have high machining accuracy, good stability, and a very uniform magnetic field. The uniformity of the uniform region is guaranteed to be 1 ~ 5 *10⁻⁴.
A Halbach array is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while canceling the field to near zero on the other side. This is achieved by having a spatially rotating pattern of magnetization.
Dexinmag series constant magnetic field permanent magnets have the characteristics of no power supply, energy saving, long-term use without heat, low cost, small size, and lightweight. Due to the fixed air gap, it has good rigidity and the magnetic field is stable, which can be used as a standard magnetic field.
Permanent magnets produce a constant magnetic field has very favorable conditions, but the structure of the single to its application is subject to certain restrictions. Our company is committed to the development of a variety of adjustable magnetic field permanent magnets so that the air gap is adjustable, the magnetic field strength adjustable, and uniform area stability, so that the function of the permanent magnet is closer to the electromagnet, making it more widely used.
Axial permanent magnets are composed of a combination of special shapes of neodymium-iron-boron magnetic block arrays. Its magnetic field central axis has through holes, high magnetic field strength, and small volume, suitable for optical experiments, and axial probe calibration.
Calibration Magnet is a permanent magnet specially designed for Hall sheet calibration. It is small in size and light in weight. It is suitable for the calibration of Hall plates with 0.1%~1% accuracy. The normal magnetic field level is 0.1T~1.1T stage, available from stock; The magnetic field can reach 3.0T.
