Adjustable permanent magnet

Permanent magnet rotating magnetic field

The permanent magnet can be made into a rotating magnetic field in the form of mechanical rotation. When the permanent magnet rotates mechanically around the center of action of the magnetic field, the direction of the magnetic field is fixed in space to obtain a sine wave magnetic field. The alternating frequency of the magnetic field polarity is adjustable from 0-7Hz, the magnetic field space is large, and the magnetic field intensity can be customized.

Axial permanent magnet

The axial permanent magnet is composed of a special-shaped neodymium iron boron magnetic block array. The central axis of the magnetic field has a through hole, the magnetic field strength is high, and the volume is small, which is suitable for optical experiments and calibration of axial probes.

Halbach Array Permanent Magnet

Dimensions Φ60*50mm Inner diameter Φ20mm Weight 1 (Kg) 12 sector-shaped magnetic blocks, each with a different magnetization direction, arranged in a Halbch circular array; The central magnetic field strength is 1.04 (T); The uniformity in the range of Φ6*6mm in the center of the magnetic field is 0.5% in the axial direction and 0.5% in the radial direction.

YC series permanent magnet

YC series constant magnetic field permanent magnets have the characteristics of no need for power supply, energy saving, no heat generation for long-term use, small size and light weight. Due to the fixed air gap, it has good rigidity and stable magnetic field, so it can be used as a standard magnetic field. The permanent magnet series have a wide range of applications, and permanent magnets can be selected according to the different requirements of instruments and equipment.

YC40 series standard magnets for calibration

YC40 series standard magnets are permanent magnets specially designed for Hall plate calibration. They are small in size and light in weight. They are suitable for the calibration of Hall plates with 0.1%~1% accuracy. Normal magnetic field grades are available in stages from 0.1T to 1.1T, available from stock; the highest; The magnetic field can reach 3.0T.
