Natural EMR/EMFs (cosmic microwaves, infrared, visible light, ultraviolet, gamma rays ) and several forms of artificially triggered electromagnetic emissions (such as from light bulbs with thermal filaments, gas discharge lamps, x-rays, lasers, etc.) are not polarized.12 Eki 2015
Read moreWhat is natural magnetic field?
The natural magnetic field is the sum of an internal field due to the Earth acting as a permanent magnet and an external field generated in the environment from such factors as solar activity and atmospheric processes .
Read moreWhat are electromagnetic fields used for?
The electricity that comes out of every power socket has associated low frequency electromagnetic fields. And various kinds of higher frequency radiowaves are used to transmit information – whether via TV antennas, radio stations or mobile phone base stations.
Read moreIs a magnetic field an electric field?
A magnetic field is not just an electric field with relativity applied , i.e. an electric field viewed from the wrong reference frame. In reality, a magnetic field is a fundamental field which can exist in a certain reference frame without needing any help from an electric field.
Read moreWhat is the relationship between electric and magnetic fields?
Both electric and magnetic fields are the consequence of the attraction and repulsion of electric charges . However, a magnetic effect is caused by moving electric charges while an electric field is caused by stationary charges.17 Haz 2020
