PURPOSE:To obtain the effect of heating by far infrared radiation and that of magnetic therapy in winter and only the magnetic therapy in summer by mounting an AC or permanet magnet for magnetic therapy at an electrical carpet. CONSTITUTION:A magnet 2 is mounted at the electrical carpet 1. As the magnet 2, the AC magnet or the permanet magnet is used. When the AC magnet is used, it is enough to branch an alternate current that flows on the heater of the electrical carpet 1, and when the permanent magnet is used, a (rare earth magnet) suitable for the magnetic therapy is used. The rare earth magnet is provided with superior magnetic flux density and magnetic coercive force, which is small in size and is suitable for the magnetic therapy requiring a strong magnetic force. As a magnetic force used in the therapy, the one of 500 to 1500 gauss is used. |
