A PECULIARITY OF THE MAGNETIZATION OF A FERROMAGNET BY AN ALTERNATING FIELD

DOI: 10.17804/2410-9908.2020.6.035-047

It has been experimentally established that the demagnetizing field of the magnetic poles formed at the ends of an open ferromagnetic cylinder decreases with increasing frequency of the magnetizing field due to a decrease in their size under the influence of the surface effect. For this reason, as the frequency of the magnetizing external field increases, the internal field in a ferromagnetic cylinder near the surface approaches it in amplitude. In addition, it has been found that the field on the surface of a ferromagnetic rod magnetized by an alternating field significantly exceeds the latter in strength with increasing frequency of this field.

Acknowledgments: The work was performed under the state assignment from The Ministry of Education and Science of Russia (theme Diagnostics, No. AAAA-A18-118020690196-3).

Keywords: alternating magnetic field, surface effect, demagnetizing coefficient, magnetic poles, surface effect, eddy currents, internal field, penetration depth, Hall effect, microchip
