Abstract
There is provided a magnetic field generator which is capable of generating a uniform magnetic field of a desired intensity easily and stably without increasing running cost. The magnetic field generator includes a pair of plate yokes. The plate yokes have opposed surfaces provided with magnetic pole respectively. The magnetic pole includes a permanent magnet group whereas the magnetic pole includes a permanent magnet group. Each of the permanent magnet groups is formed substantially in a disc like shape, as an integral body made of a plurality of permanent magnets and a plurality of heat conducting members. Tubular heaters, buried in the plate yokes, generate heat, which is conducted via the plate yokes to each permanent magnet and each heat conducting member which constitute the permanent magnet groups.
