Question about rf signals(yes i think this does relate to physics)

[Scarlet~Witch]

i briefly read that magnetic ferrites can block rf signals. if so, how. what range limit if any is there on the ferrrite.. or did i post this question in the wrong area if not the wrong forum? I'm really REALLY curious about this. if I've gotten this wrong. well, I'm sorry.
thanks for your time..

Ferrites are commonly used in RF applications - mainly to choke off interference. Have a look at http://audiosystemsgroup.com/publish.htm - I'm sure you'll find plenty to interest you there.

Hi Scarlet,

Thank you for your question about RF signals and magnetic ferrites. This is definitely a topic that relates to physics, so you are in the right place to ask your question.

To answer your question, yes, magnetic ferrites can block RF signals. This is because they have a high permeability, which means they can absorb and redirect the energy of the RF signal. This absorption and redirection results in a decrease in the strength of the signal, effectively blocking it.

The range limit of a ferrite depends on its composition and size. Generally, the larger the ferrite, the better it will be at blocking RF signals. However, there is no specific range limit for ferrites as it also depends on the strength of the RF signal and the distance between the ferrite and the source of the signal.

You have not posted your question in the wrong area or forum. This is a relevant topic and I'm sure many others are also curious about it. I hope this helps answer your question. If you have any further questions, please don't hesitate to ask.
