In this way, an un-dead soft steel plate that has a low carbon content gets coated with nickel and shaped into a yoke with multiple upward pole teeth 31a as well as plural downward pole teeth 32a in its peripheral part. The whole structure is then annealed to temperatures in the range of 7

This is especially true for endothermic reactions or those that produce a large amount of heat. If the heat is not removed in time, the reactor may runaway and require a power compensation system.
