    Detectors Monopole
AI Thread Summary
Superconductors are essential for detecting monopoles due to their sensitivity to subtle electrical fields and voltages, surpassing traditional methods like EEG. EEG machines measure voltages but may not effectively detect monopoles, as their unique properties could lead to cancellation effects. The discussion raises questions about the feasibility of using EEG for monopole detection, with participants emphasizing that superconductors provide a more reliable solution. Concerns about the limitations of EEG in this context are acknowledged, reinforcing the preference for superconductors in monopole detection. Understanding the underlying physics is crucial for grasping why superconductors are favored over other detection methods.

Why does a monopole detector have to be a superconductor?

If there were Monopoles. Why couldn't an EEG machine detect them. Remember in monopoles, moving magnetic charges would generate electric fields. If say the monopole is very strong, it should make the EEG detect them by the probe just hanging in the air, is it not? Or no matter how strong monopoles are, no EEG can detect them and only superconductor? Why?

Btw. What is more sensitive than an EEG to detect subtle electrical fields and voltages?

A superconductor.

If monopole existed in the low energy sector. Can an EEG detect them? Or maybe never at all because the current of the monopole somehow cancels each other out?
Please clarify the issues because I'm still confused. Thanks.
 
You asked a question, and got an answer. You seem not to like the answer, but that's not the same as being confused.
 
My new question now is. If monopole existed in the low energy sector. Can an EEG detect them? Or maybe never at all because the current of the monopole somehow cancels each other out? Can anyone else answer this? Thank you.

I don't really see why not but why are you asking? Are you trying to build a detector? Superconductors will detect them in more detail than an EEG. So why not just use the superconductor?

No. I just want to understand it. Nothing bad about trying to know.

EEG measures voltages. If there were monopoles running around. How could EEG measure them at all??
 
Asked and answered.

Could you build a detector out of less-than-optimal parts? Sure. But why? You could probably make one out of a coat hanger and chewing gum. Again, but why?
