An auxiliary heater is provided for heating a heat transferring fluid to a high temperature efficiently in a short time. The heater includes a permanent magnet provided within a housing and a rotary water jacket made of a conductor positioned to face the permanent magnet leaving a slight gap therebetween. The conductor generates slip heat when the water jacket is rotated in relation to the permanent magnet. The heat transferring fluid within the housing is heated by the slip heat generated in the conductor.

[ What is claimed is:] [1.]1. A magnetic heater of the type in which a magnet and a conductor are disposed so as to face to each other leaving a slight gap and heat transferring fluid is heated by slip heat which is generated in said conductor by relatively rotating said magnet and said conductor, wherein said magnetic heater comprising:a permanent magnet fixed to a housing supported to a driving shaft via a bearing; anda flat disc-like conductor facing to said permanent magnet while leaving a slight, constant gap provided rotably to said driving shaft within said housing;the heat transferring fluid introduced to the inside of said housing being in fluid communication with said disc-like conductor, said heat transferring fluid being heated by the slip heat generated in said conductor as said disc-like conductor rotates.
