What electromagnetic range would disrupt a neodymium magnet?

Click For Summary

Discussion Overview

The discussion revolves around the effects of electromagnetic radiation on neodymium magnets and the challenges of detecting and measuring such radiation. Participants explore the feasibility of using a neodymium magnet to disrupt electromagnetic sources and the appropriate methods for measuring unknown frequencies.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant questions whether a neodymium magnet can disrupt electromagnetic radiation, suggesting it may interfere with the detection device instead.
  • Another participant proposes that a "super wide spectrum" frequency detector might be necessary to obtain readings from an unknown electromagnetic source.
  • A participant clarifies that jamming requires emitting more electromagnetic radiation of the same kind, indicating that a permanent magnet would not serve this purpose.
  • Details about the frequency range of the participant's detector are shared, indicating it covers low frequencies from 5Hz to 400KHz and high frequencies from 30MHz to 2000MHz.
  • Concerns are raised about the legality of the intended jamming actions, with one participant expressing skepticism about the legality of the proposed activities.

Areas of Agreement / Disagreement

Participants express differing views on the effectiveness of neodymium magnets in disrupting electromagnetic sources and the methods for detecting such radiation. The discussion remains unresolved regarding the feasibility of the proposed detection and jamming methods.

Contextual Notes

Participants acknowledge the limitations of their knowledge regarding the specific devices involved and the potential legal implications of their actions. There is uncertainty about the nature of the electromagnetic source in question.

Hello all,

This is just a question i have... I need to know the frequency (in order to meter it) from an electromagnetic source, and i know that a neodymium magnet will disrupts it. so, i want to know what range the neodymium will disrupt, in order to know what device will need to meter source. Is this possible? or, how can i meter an electromagnetic source if i don't know what frequency is using this source? I have a chinese cheap microwave/EMF detector but seems like won't detect it.

Thanks in advance

As my english isn't perfect, let me know if i wasn't clear enough

I'm not sure this is possible. Your magnet doesn't disrupt the EM radiation itself, it actually messes with whatever device your are using to emit the radiation. Either that or your detector. Without knowing the detailed specifics of your devices this may not be possible. And even then it may still not be possible.
 
Well i didn't put the magnet near the device. It was pretty far (the device is supposed to work as "focus" it's EM emission) i think you are right and it's possible that won't disrupt it, magnet it's probably affecting the target device.

Then it's impossible? should i seek for a "super wide spectrum" frequency detector in order to have some readings?

Welcome to the PF.

It would help a lot if you could post some pictures of the setup, along with details of what each device is, and what you are trying to do.
 
Well i do not own the transmitter device so this is like reverse engineering, a black box situation. I'm trying to do it in order to find the frequency (i know this could be impossible) or a range in order to disrupt it with a a kind of jammer device OR AT LEAST some readings from it's EM emission as i don't even know what range is using.

My detector

Measure frequency range: low frequency:5Hz-400KHz, high frequency: 30MHz-2000MHz.

I used it in order to test common EM radiation, like MW from wireless networks, cellphones, wireless phones etc... and low EM freq as computers, tv's. But as isn't common frequency i probably need something else.

It's not illegal
 
You do realize the only way to jam something like this is to send out MORE EM radiation of the same kind right? That's how jammers work. A regular permanent magnet is not going to jam anything. The only thing it might do is possibly mess up your receiver if you get it too close.

What are you trying to jam? Is there a cell tower or radio tower nearby? Or do you not know what it is at all?

I'm not convinced that what you are wanting to do is not illegal. Thread closed. PM me with a *lot* more details, and I may re-open the thread.
