Magnetic Flux Q&A: Can Length Contraction Alter Quanta?

Click For Summary

Discussion Overview

The discussion revolves around the relationship between magnetic flux and length contraction, particularly whether length contraction can alter the quanta of magnetic flux generated by a magnetic field source. Participants explore theoretical implications and the nature of magnetic flux and Planck length.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions if moving relative to a magnetic field can alter the quanta of magnetic flux, suggesting that it might be possible to achieve half of the flux through length contraction.
  • Another participant asserts that magnetic flux is a scalar quantity that remains unchanged under Lorentz boosts, as changes in the magnetic field and area compensate for each other.
  • A participant introduces the concept of Planck length, prompting a discussion about its significance.
  • Another participant responds that Planck length is merely a unit of measurement and suggests that at such scales, space-time might behave differently.
  • One participant speculates that if a minimum length exists, it could be possible to achieve length contraction by moving at a certain speed, although they express uncertainty about its relevance.

Areas of Agreement / Disagreement

Participants express differing views on the impact of length contraction on magnetic flux, with some asserting that it does not change while others propose alternative ideas. The discussion remains unresolved regarding the implications of Planck length and its relationship to the topic.

Contextual Notes

There are unresolved assumptions regarding the nature of magnetic flux and the implications of length contraction, particularly in relation to quantum scales and Planck length.

Can I alter the quanta of magnetic flux using length contraction of the source creating the B field. Like for example could I get half of the flux by moving relative to the B field. Or some other fraction of it. The unit of flux is like [itex]\frac{h}{2e}[/itex]
 
Physics news on Phys.org
The magnetic flux is actually a scalar quantity which doesn't change from Lorentz boosts. This is because while the magnetic field changes, the area also changes in exactly compensating ways.
 
ok interesting, what about the Planck length
 
What about it? It's just a unit of measurement, like the meter. It doesn't really mean anything special except we expect that at those lengths (i.e. order of magnitude near the Planck length), space-time might look different.
 
If there is a minimum length, then i could just move by it a speed and length contract it.
Or maybe this doesn't matter.
