LHC and the Earth's Magnetic Field

Click For Summary

Discussion Overview

The discussion centers on the potential impact of the magnetic field generated by the Large Hadron Collider (LHC) on the Earth's magnetic field. Participants explore the strength and reach of the LHC's magnetic field in relation to the Earth's magnetic environment.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions whether the LHC's magnetic field could affect the Earth's magnetic field.
  • Another participant notes that the LHC's magnetic field is very strong within a small volume where the beams circulate but is negligible outside that area.
  • A similar point is reiterated by another participant, emphasizing the lack of sources to support their claims.
  • One participant provides specific figures, stating that the LHC's magnets produce a field of about 8.5T, which is less than what can be achieved in large lab NMR machines and significantly lower than the record for sustained or pulsed fields.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the potential effects of the LHC's magnetic field on the Earth's magnetic field, and multiple viewpoints regarding the strength and impact of the LHC's magnetic field are presented.

Contextual Notes

Some limitations include the lack of sources to substantiate claims about the magnetic field's effects and the specific conditions under which the LHC's magnetic field operates.

I was curious as to whether or not there is potential for the magnetic field generated by the LHC to affect the Earth's magnetic field...

The magnetic field of the LHC is very strong *inside* a small volume where the beams circulate, but is rather negligible outside. I tried to find some sources, but didn't find any.

lol same...and I was thinking the same but seeing how I could not find anything I figured I would ask.
 
The LHC's magnets are only about 8.5T - you can get twice that in large lab NMR machines.
The record for a sustained field is around 35T you can get about 100T pulse with an exploding system.
 
Thank you.
