To study the effects of various factors, such as different carriers, with or without ground connection to a blanket and status of its switch, on electromagnetic field induced. To determine electric field, magnetic field and electric current on human bodies induced by electric blanket with a temperature--adjustable semiwave rectifier diode, which was domestically popular. Temperature was adjusted and controlled by a diode serially connected to its switch is put on and the blanket, with or without short circuit. When the switch is put on and the blanket is running in low temperature, if the diode is serially connected to the ground end of the power source, the intensities of electromagnetic field and current on the human bodies induced by the blanket was higher than those running in high temperature. The most important factor influencing field intensities of the electric blanket is in its switch.
