電磁波,又稱電磁輻射,是指同相振盪,且互相垂直的電場與磁場,在空間中以波的形式傳遞能量和動量,其傳播方向垂直於電場與磁場的振盪方向。電磁波會散發出一種擾亂人體狀態的正離子。
日常生活中有很多看不見的電磁波,除了行動電話的 電磁幅射外,一般家庭所使用的電器商品也有一定的電磁幅射。電磁波過敏症更是2006年由世界衛生組織發布之新疾病,為由電磁波所引起的各種症狀。

In physics, electromagnetic radiation (EM radiation or EMR) refers to the waves (or their quanta, photons) of the electromagnetic field, propagating (radiating) through space, carrying electromagnetic radiant energy. Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields
