The utility model comprises a blanket, electrothermal conducting wires, a switch and a rectifier filter which is electrically connected between the switch and a heating cord, wherein the electrothermal conducting wires are made into field coil type to be distributed in the blanket. The alternating current is converted into the direct current by the rectifier filter, and a stable constant magnetic field is generated around field coils. The direct current and the stable constant magnetic field are converted into heat, and the heat is generated softly. The utility model overcomes the defects of the existing electric heating blanket, and is favorable for warming and caring health of the human body.
