Permanent Magnet
Constant Magnetic Field

The features of constant magnetic field:
 
     * Without power supply, saving energy, without  heating when using for long time, small volume and linght weight, low price;
     * Air gap fixed with good rigidity, stable magnetic  field, could be used as standard magnetic field;
     * Wide application, could be chose according to the  different requirements of  instrument and  device. It is the best choice for devices that require high precision, such as  NMR.
We could customize different shapes permanent magnet according to customers’ special requirements.
