Home Electric Appliances

Home electric appliances that use electricity, such as TVs, refrigerators, and electric blankets, emit electromagnetic fields at a frequency of 50/60 Hz (hertz).

However, in the case of products that contain motors, such as hair dryers and vacuum cleaners, the rotation of the motor generates magnetic fields from several kHz (kilohertz) to several hundred kHz.

The Magnitude of Magnetic Field Generated from Home Appliances

Measurements conducted by JEIC have revealed that the magnetic fields generated from various home electric appliances are lower than the international exposure limit of 200 µT (microteslas) established by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).

Scientifically Established Effect to Humans Caused by Magnetic Fields Generated from Home Appliances

Magnetic fields generated from home electric appliances and encountered in living environments have no effect on humans. Only when exposed to very strong magnetic fields, several hundred times greater than those encountered in daily life, might nerve and muscle activities be affected due to the phenomenon called electromagnetic induction. And much stronger magnetic fields are known to influence heart function. For more details, please, refer to the provided source here.

In daily life, even when multiple home electric appliances are used simultaneously, the strength of magnetic field rapidly decreases with distance from the source, ensuring remains well below the exposure limit values of the international guidelines.
