Highly intensive sources of permanent magnetic field

On basis of NdFeB permanent magnets a compact magnetic system permitting to get highly homogenous magnetic field up to 2 - 3 T inside a cylindrical cavity was designed. The system is an economic and effective alternative to electromagnetic sources of permanent magnetic field and can be used in scientific and applied researches conducted under application of highly intensive magnetic fields.
