hello, I was just thinking since a photon trajectory is affected by a magnetic force.then I would like to know how much force does it take to do just so.
ectro said:well its a built up conclusion from various textbooks.
if does not then what would effect its trajectory ?
ectro said:Thanks to whom replied and corrected my conclusion. Now since its affected by gravity then how would I if possible to create an artificial field of gravity
ectro said:well, what about theories?

Drakkith said:I think the OP is asking about something that would change the path of light like a normal gravitational field would. This would not.
DrDu said:In matter this can be observed: A magnetic field can change the index of refraction in certain directions which leads to a refraction of the light passing through that material . Search wikipedia for Faraday and Kerr effect.
I am convinced that sufficiently strong magnetic fields will theoretically also interact with light in vacuo.
However, these effects from quantum electrodynamics are extremely small and have not jet been detected experimentally.
ectro said:so we would need a very powerful force fo gravity to alter the path if the light can we use magnetic force as such.
Drakkith said:I'm not talking about the difference between two reference frames, I'm talking about changing the direction of light. This change would appear in BOTH frames.
mrspeedybob said:Consider a beam of light traveling through a free falling elevator. An occupant of the elevator will see a straight beam while someone standing on the floor will see a beam curved due to gravity. Curvature is not frame independent.
The path of the photon relative to what? Locally, acceleration is indistinguishable from gravity.Drakkith said:But we are not talking about how it appears, but about actually changing the path of the photon. This requires a real gravitational field.
HallsofIvy said:The path of the photon relative to what? Locally, acceleration is indistinguishable from gravity.
Drakkith said:Gravity would, along with interactions with just about any material.
Neandethal00 said:Is it safe to say, magnetic field does not affect path of a photon because photons have no mass ? I do not see any other reason why photons are unaffected by magnetic or electric field.
A magnetic field may change the polarization of light (electro-magnetic wave) due to interaction between two magnetic fields. Any such experiments?

The magnetic force acting on a photon is directly proportional to the change in its trajectory. This means that the stronger the magnetic force, the greater the alteration in the photon's path.
The amount of magnetic force does not affect the speed of a photon. According to the laws of physics, the speed of light is constant and cannot be altered by any external force.
Yes, a strong enough magnetic force can completely change the direction of a photon. However, this is only possible if the force is applied at a specific angle and with enough strength to overcome the photon's momentum.
Yes, the amount of magnetic force needed to alter the trajectory of a photon depends on its energy and wavelength. Higher energy photons require more force to change their trajectory compared to lower energy photons.
The presence of other magnetic fields can affect the amount of force needed to alter a photon's trajectory. If the photon is already traveling through a magnetic field, the force needed to change its trajectory will be greater. Additionally, if there are multiple magnetic fields present, they can interact and affect the overall force on the photon.
