Can we produce magnetic field from stationary charge?

Click For Summary
SUMMARY

The discussion centers on the impossibility of generating a magnetic field from a stationary charge. Participants confirm that magnetic fields arise only from moving charges, time-dependent electric fields, or the intrinsic spin of particles. The principle of equivalence is mentioned, suggesting that even in oscillating gravitational fields, stationary charged particles do not produce magnetic fields. The consensus is clear: without motion or variation in electric fields, magnetic fields cannot be produced.

PREREQUISITES
  • Understanding of electromagnetic theory
  • Familiarity with the principles of charge and magnetic fields
  • Basic knowledge of quantum mechanics and particle physics
  • Concept of the principle of equivalence in general relativity
NEXT STEPS
  • Research the relationship between moving charges and magnetic fields
  • Explore time-dependent electric fields and their effects on magnetic field generation
  • Study the principle of equivalence in general relativity
  • Investigate the intrinsic magnetic moments of subatomic particles
USEFUL FOR

Physicists, electrical engineers, and students of electromagnetism seeking to understand the fundamental principles of magnetic field generation and the behavior of charged particles.

Dear all, I know the sources of magnetic field are moving charges or varying electric field. I also know that subatomic particles(even neutron) have their own magnetic moment due to its quark and spin and their magnetic moment is explained by invoking quantum mechanics(though I don't know how because to be true I do not have detailed knowledge of the subject of quantum mechanics). However my question is not about the intrinsic magnetic moments of subatomic charge particles but about some charge at rest. Suppose I have a charge particle at some point in space and I can say at some other point in space there is an electric field that's fine. Now my question is can I get a magnetic field at some point due to this charge without making the charge in motion?

No.

You need motion, time-dependent electric fields, or the spin of particles to have magnetic fields.

Thank you :)

One more thing to ask, Isn't there a way to produce time-varing electric field without moving the very charge?
 
Electromagnetic radiation, if you ignore where this radiation would come from. Apart from that: No.
 
I am not sure but believe that if a charged particle is stationary in an oscillating (e.g. sinusoidal) gravitational field then it will radiate.

At least that is what the principle of equivalence predicts.

In any case take any radiating particle. You can always observe it from within its rest frame. I believe it will still radiate.

That rest frame is not an inertial frame then.

If charged particles following geodesics radiate (e. g. if they make a hyperbolic orbit around a star) is still discussed.

It will not, it does not, and it will not.
