Induction radio waves
Web4 aug. 2014 · At the receiving antenna, the time varying field induces a current in the receiving antenna,and as a result, a detectable voltage. So the electron flow is confined to within the transmitting and receiving antennas, and what is flowing between the antennas is electromagnetic fields, not electrons. WebElectromagnetic shielding is the process of lowering the electromagnetic field in an area by barricading it with conductive or magnetic material. Copper is used for radio frequency (RF) shielding because it absorbs …
