Magnetic design - Import export

This magnetic system is specially designed for non-destructive testing of pumped vacuum devices, that required the creation of a uniform magnetic field not only in the center of the operating bore, but in the toroidal region of large size. The system is assembled on the basis of NdFeB permanent magnets.

The compact system of permanent magnets NdFeB, designed according to the principle of the dipole Halbachstructure, allows to get, inside the bore, rather homogeneous magnetic field with the magnetic flux density up to 23 Tesla. The system can be an efficient alternative to electromagnetic sources of the magnetic field, and can be used in scientific and applied research requiring magnetic fields of high intensity. Geometrical dimensions and magnetic flux density in Halbachtype systems can vary widely, the attached data and photos are typical examples. AMT&C LLC offers the manufacturing of steady magnetic field systems according the customer technical specifications. To improve the temperature stability the system can be assembled of SmCo magnets.

For testing cardio-stimulators and other medical devices, a set of the magnetic field sources was designed having a magnetic flux density in the working area from 1 to 300 mT.
