PURPOSE:To make a heat generating magnetic field come in contact with the entire external surface of heating articles and enable heating the articles with relative unformity and likewise from the external part thereof almost without any effect due to a shape by providing a magnetic fluid for generating heat via a hysteresis loss, a non-magnetic fluid vessel for containing the magnetic fluid and an alternating magnetic field generator for applying an alternating magnetic field to said magnetic fluid. CONSTITUTION:A magnetic fluid 1 (liquid, powder or grains) is contained in a non-magnetic vessel 2 and heating articles 4 and 5 are put in the magnetic fluid 1. In this condition, an alternating magnetic field is applied to the magnetic fluid 1 with an alternating magnetic field generator 3. As a result, the magnetic fluid 1 generates heat due to the hysteresis loss thereof and the heating articles 4 and 5 in contact therewith are directly heated. |
