Why don't radio waves interact with magnetic fields?

AI Thread Summary
Radio waves, including TV, Wi-Fi, and other GHz transmissions, do not interact with static magnetic fields due to the nature of electromagnetic waves. While electromagnetic waves can pass through each other and static fields, a permanent magnet does not emit electromagnetic waves but instead creates a dipole field. The interaction between electromagnetic waves and magnetic fields is governed by established physical laws, which indicate that these waves are not influenced by static magnetic fields. The discussion emphasizes that the lack of interaction is simply a characteristic of how these physical laws operate. Understanding this principle clarifies why radio signals remain unaffected by permanent magnets.

I've been told that magnetic field does not mask or influence any GHz transmissions; TV, Radio, Wi-Fi, etc. and should not pose a problem. Can someone explain why they do not interact? Credible documentation such a law or theory? Educational documentation? Thanks in advance.

Superposition principle
Electromagnetic waves travel through each other and through static fields.
 
Thanks for the reply, however, I'm referring to the field of a permanent magnet. Not an electromagnetic wave.
 
as said ...

EM interaction with an EM wave isn't any different to an EM interaction with a Magnetic field

Correct, but a permanent magnets does not emit electromagnetic waves but rather a gravitational force due to the dipole field, from what I understand. Are electromagnetic waves affected by the magnetic field? If not, why not?

read Khashishi's and my previous post again ... they both answer you Q

and gravity has nothing to do with it ...Dave

All of those signals are EM waves. These waves simply don't interact with a static magnetic field in such a way as to be influenced by it. Note that asking why something doesn't happen is hard to answer. The simple answer is that that's just the way the laws work.
