Although a magnetic field doesn’t affect the photons of light directly, a magnet can distort the medium through which light passes and thereby “bend” the light rays. Light travels through space-time along a geodesic – the shortest possible path between two points on a curved surface.
The quantum theory shows that light is made up of photons which do not carry charge, during to which it is unaffected by electric or magnetic fields.
Everybody knows that light travels in straight lines, but while that is its natural tendency light can be deflected by lenses, mirrors, and by gravitational fields.
Unlike silver and other metals, however, there is no natural material that reflects light magnetically. Magnetic fields can reflect and even bottle-up charged particles like electrons and protons. But photons, which have no charge, pass through freely.
According to theory of properties of photon, they can not be affected by electric and magnetic fields and it is neutral.
Can light be deflected by electric field?
Solution : Light being an electromagnetic wave, does not consist of charged particles. Hence light is not deflected by electric or magnetic fields.

Can a magnet reflect light?
Unlike silver and other metals, however, there is no natural material that reflects light magnetically. Magnetic fields can reflect and even bottle-up charged particles like electrons and protons. But photons, which have no charge, pass through freely.
Can a magnetic field deflect a photon?
Photons are electrically neutral and are not deflected by electric and magnetic fields.
Is light affected by electric field?
The path light takes is not usually affected by the presence of a magnetic field. Light itself is composed of an oscillating electric and magnetic field, and one very important property of electric and magnetic fields is what we call “linearity.”
Can light be deflected by magnetic field?

Which is not deflected by electric field?
Gamma rays are chargeless. So they cannot be deflected by electric or magnetic fields.
Can light be deflected by a magnet?
The short answer is that only charged particles like electrons or protons are bent when travelling through magnetic fields. Electromagnetic radiation is made up of uncharged photons, so is unaffected.
Can photon be deflected?
Photons are electrically neutral and are not deflected by electric and magnetic fields.
What Cannot be deflected?
Neutrons are neutral particles and does not carry any charge, thus cannot be deflected by electric field.
Can a magnet make a lightbulb light up?
Whenever you bring coils and magnets together (in the proper orientation and moving with respect to each other), magic happens. In this case, it is the Edisonian magic of lighting a light bulb. Turning the crank rotates a coil inside of the large U-shaped magnets.
Can a magnet produce light?
Technically, yes. The changes in magnetic and electrical fields will propagate outwards at the speed of light. The wavelength is determined by the frequency, so it would depend on how fast you were spinning the magnet.
Can light be manipulated with magnets?
Now, a team of theoretical physicists from the University of Exeter have demonstrated that it is possible to create synthetic ’magnetic fields’ for light by distorting honeycomb metasurfaces: surfaces with structures on a scale smaller than the wavelength of visible light, which can be used to manipulate the …
Can photons be affected by magnetic fields?
They only interact with charged particles, and not with each other. That’s why photons don’t interact with magnetic fields — the photons which make up the magnetic field are not charged so other photons cannot interact with them.
What happens to a photon in a magnetic field?
Magnetism has nothing to do with being able to reflect light from a surface. But magnetic fields do not deflect light rays, so a magnet will not bend light because of its magnetic field.
Can magnetic field deflects light?
Photons do not have any charge, so they are electrically neutral. Hence, photons are not deviated by electric fields and magnetic fields.

Is light deflected by external electric and magnetic field?
These fields do not carry charge, and it is only charge that is deflected/senses electric and magnetic fields. Classically, there can be superposition of two waves which show interference patterns, but superposition is not interaction. The classical electromagnetic wave interacts only when it sees charges (and,possibly, magnetic dipoles).
Can a light be bent by a magnetic field? – Physics Stack Exchange
is yes it can be bent due to the curvature of spacetime produced by a strong magnetic field. I can give a very short answer why, without going into too much detail, how the resulting bent geodesics might look. Einstein’s field equations state: G μ ν = 8 π T μ ν, Energy-Momentum curves spacetime.

Magnetic Deflection – an overview | ScienceDirect Topics
Amplifying valves control the flight of electrons by imposing electric fields, but electrons can be deflected by magnetic fields. The Earth’s magnetic field is quite weak, so it is unlikely that orienting a valve in any particular direction will affect distortion, but most sheet electrodes are made of nickel, which can easily be magnetised.
Deflection and Delay of Light
Currently the deflection of “light” is best measured using radio astronomy, since radio waves can be measured during the day without waiting for an eclipse of the Sun. Lebach et al.

Can a magnet bend a ray of light? – Physics Forums
The simple answer is no. The magnetic field of an ’everyday magnet’ is not energetic enough to produce gravitational effects sufficient to ’disturb’ a ray of light. Light and magnetism are both aspects of the electromagnetic force. A handheld magnet can strongly bend an ’electron beam’, but not even slightly bend a light beam, and a flashlight …
