| 摘要 |
The invention provides a heating apparatus including a holder capable of holding at least one part, an electric current generator and a flux concentrator electrically connected to the electric current generator. The flux concentrator is made of a non-magnetodielectric material and having a coil with at least one turn forming an inductor to generate an alternating magnetic field that is driven by the alternating electric field. The alternating magnetic field resonates at a frequency of at least 1 MHz in response to the alternating electric current. A plurality of flux concentrators and at least one part may be held in proximity to one another. One or more alternating electric current may be generated to generate a plurality of alternating magnetic fields by the respective flux concentrators. |
