Magnetic Field vs Spacetime: Effects on Inertia Disk

Click For Summary

Discussion Overview

The discussion revolves around the effects of magnetic fields on spacetime and their potential influence on an inertia disk, specifically a gyroscope, that is partially situated within a magnetic field. Participants explore the implications of these effects on propulsion and angular momentum without mass variation.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant suggests that a magnetic field can produce a minimum distortion in spacetime, potentially affecting an inertia disk spinning within it.
  • Another participant expresses confusion regarding the terminology used, specifically "inertia disk" and "unbalanced in the angular disk moment."
  • A participant clarifies that they are referring to a gyroscope and questions how a high-density electric or magnetic field might interfere with spacetime and affect the gyroscope.
  • It is proposed that the energy from an electromagnetic field produces spacetime curvature, though the effect is expected to be extremely small for fields generated by humans.
  • Concerns are raised about conservation laws, with one participant stating that any effect on the gyroscope would be countered by an equal and opposite effect on the field and its source.
  • Another participant challenges the concept of a spatially limited field, noting that magnetic and gravitational fields do not have sharp boundaries and fall off gradually.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of propulsion without mass variation and the implications of conservation laws. There is no consensus on the validity of the initial claims regarding the effects of magnetic fields on spacetime and inertia disks.

Contextual Notes

Participants highlight limitations in understanding the terminology and concepts involved, as well as the complexity of field interactions and conservation laws. The discussion remains open-ended regarding the specific effects of magnetic fields on spacetime.

TL;DR
Propultion without mass variation
By following article a magnetic field can produce a least a minimum distortion in spacetime.

If we have a inertia disk spinning 50% inside of a strong closed magnetic field may we suppose that we will create an unbalanced in the angular disc moment producing a propulsion without mass variation since 50% of inertia disk is isolate inside of magnetic or electric field?

I’m not completely understanding your question here. What do you mean by “inertia disk”? Or “unbalanced in the angular disk moment”? Neither of those phrases make sense.

something like a gyroscope

The main question is how much a high density electric or magnetic field can interfere with spacetime in order to affect a Gyroscope that is 50% inside this field and 50% outside.

how much is wrong sorry. How many?

No, how much is correct. The effect you are asking about is continuous.

I assume that by "interfere with spacetime", you are referring to the fact that an electromagnetic field has energy, and energy produces spacetime curvature. This is true, but the amount of spacetime curvature produced by such a field will be extremely small for any field that can be produced by humans.

Also, any effect on a gyroscope would be balanced by an equal and opposite effect on the field itself and its source. You can't violate conservation laws.

No. As @PeterDonis mentioned you cannot violate the conservation laws.

In addition, I think that your concept of a spatially limited field is more than a little problematic. Both magnetic fields and gravitational fields don't have sharp boundaries. A typical magnetic field falls off as ##1/r^3##. Although you can make it fall off faster through careful engineering, it is going to be at some level a smooth and gradual transition. The resulting gravitational field will be even smoother and fall off slower.

However, none of that matters with respect to propulsion. There it is the conservation laws that are the problem.
