Nd-Fe-B and Sm-Co magnets were irradiated by electron beam with the energy of 10 MeV and bremsstrahlung. The absorbed dose was 16 and 160 Grad. It was found that magnetic flux of Nd-Fe-B magnets decrease with irradiation, whereas Sm-Co magnets keeps magnetic performance. Проведено дослідження зміни...
