Electromagnetic radiation transformation for powered devices is described. In embodiment(s), a wireless phone (e.g., a cellular phone) includes one or more sources that emit electromagnetic radiation, such as an internal power supply or antenna system of the wireless phone. The wireless phone can also include a paramagnetic material in a quantity sufficient to counteract the electromagnetic radiation emitted by the source. To counteract harmful effects of the electromagnetic radiation, the paramagnetic material can transform the electromagnetic radiation, such as to effectuate a frequency transformation and/or to alter an intensity of the electromagnetic radiation.
