CASE OF PRECISE RESONANCE DURING MOVEMENT OF CHARGES IN A SLOWLY VARYING SPATIALLY MODULATED MAGNETIC FIELD (SLUCHAI TOCHNOGO REZONANSA PRI DVIZHENII ZARYADOV V MEDLENNO MENYAYUSHCHEMSYA, PROSTRANSTVENNO-MODULIROVANNOM MAGNITNOM POLE),
The author considers the motion of charges in a cylindrically symmetric magnetic field which is a superposition of two fields, viz. a strong field, and a weak field. Only particles with trajectories passing through the axis of symmetry of the system are considered. It is found that an increase in radial field intensity with radius causes a more rapid change in the fundamental field in the case of exact resonance since this field amplification with coordinate r amounts to the same thing as increasing the depth of modulation.
