1. A magnetic field generating apparatus operating in conjunction with a radiation treatment device for treating affected tissue of a subject by using photon beam radiation, the apparatus comprising:
a magnetic field generating unit configured to form a magnetic field inside the subject; and
a synchronization control unit configured to synchronize a radiation pulse corresponding to the photon beam radiation with a magnetic field pulse corresponding to the magnetic field,
wherein the synchronization control unit sets a magnetic field generation time range such that a secondary electron generation section generated due to irradiation of the photon beam radiation is included in the magnetic field generation time range after the magnetic field reaches a target value.
