Discussion Overview

The discussion revolves around the feasibility of creating plasma and a plasma laser using strong magnets in a vacuum. Participants explore the conditions necessary for plasma formation, the role of gases, and the implications of temperature on the process.

Discussion Character

  • Debate/contested
  • Homework-related
  • Exploratory

Main Points Raised

  • One participant proposes using strong magnets in a vacuum to create plasma and a laser.
  • Another participant argues that simply placing magnets in a fixed position does not lead to plasma formation, citing conservation of energy.
  • A participant expresses doubt about creating plasma from a vacuum, noting that current technology typically requires strong electromagnetic fields applied to gases.
  • There is confusion regarding the term "Jew strong," with participants seeking clarification on its intended meaning.
  • One participant suggests that using two strong diamagnetic magnets in a vacuum filled with hydrogen at low temperatures could lead to plasma formation.
  • Another participant challenges the idea of a vacuum being filled with hydrogen, questioning the consistency of the terms used.
  • Concerns are raised about the temperature mentioned (273.15 K), with a participant noting it is not particularly low and questioning the expectation of lasing under those conditions.
  • A later reply emphasizes that one cannot expect desired outcomes from random combinations of materials and suggests the thread may not be helpful.

Areas of Agreement / Disagreement

Participants generally disagree on the feasibility of creating plasma and a plasma laser under the proposed conditions. Multiple competing views remain, particularly regarding the definitions and requirements for plasma formation.

Contextual Notes

There are limitations in the clarity of terms used, such as "vacuum" versus "vacuum filled with hydrogen," and unresolved assumptions about the conditions necessary for plasma creation.

Homework Statement: So if I were to take Jew strong very strong magnets and place them repelling one another in a vacuum would I be able to create plasma and could I create a laser that can shoot it out?
Homework Equations: sorry new to this

:biggrin:

No. Why would you expect so?

If you just put magnets somewhere in a fixed position and nothing else then nothing happens. You can see this e.g. from conservation of energy.
 
Plasma is one of the four fundamental states of matter (the other three being gas,liquid,solid) and thus I doubt that it can be created from vacuum. Current technology creates plasma by applying strong electromagnetic field to various types of gases. Maybe you ll find the entry on plasma in Wikipedia informative and usefull:

What is jew strong? I assume you didn't mean a racial slur, so what did you mean?

...take two strong (very strong) magnets...

I moved it out of the homework forum because I'm quite sure this was not a homework problem.
 
sorry my phone mic is stupid
 
Yes two strong magnets in a vacuum, would it create plasma?

Sorry, very new to this site and thanks for moving my post

You have already been answered. No. See post #2. Plasma is matter. Magnets are not going to create matter from nothing.

What is that video supposed to show?

right, so then two strong diamagnetic magnets in a vacuum filled with hydrogen while being cooled to 273.15 kelvin

What the *&$(&#) ? A vacuum AND filled with hydrogen?. Please make up your mind what you are talking about !

to make plasma you need a gas so I gave you one, plus I want to know if under very low temperatures the hydrogen when becomes a super fluid what will actually happen

But you also said it was a vacuum.

273K isn't a particularly low temperature - it's about the melting point of ice. And mfb's answer in post #2 stands as far as I can see. Why would you expect this to lase?

You can't just randomly put together some stuff and then expect whatever you want to be produced. That's not how the real world works.
As this thread isn't going to be helpful to anyone I closed it.
