LLC "AMT&C" offers automatic measuring system (AMS) for measurements of the magnetocaloric effect and other magnetic parameters. AMS includes: - Halbach-type magnetic field source with changing magnetic field based on permanent NdFeB magnets, - liquid nitrogen cryostat, - the set of measuring inserts, - data acquisition and measurements control system guided by a control computer. AMS has the following working parameters: - variable magnetic field strength - from -1.85 to +1.85 T, - variable frequency of the magnetic field change from 0.1 to 1.8 Hz (magnetic field change rate from 0.05 to 6 T/s), - dimensions of the magnetic field area with heterogeneity no more than 1 % - diameter 20 mm, length 20 mm, - working temperature region – 80 ÷ 365 К, - automatic and manual measuring modes. The basic option of AMS is the magnetocaloric effect measurement. - sample dimensions (min-max) (1-2)×(2-5)×(8-10) mm, - measurement accuracy of magnetocaloric effect: 0.1 K.

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.

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.
