Mar 6, 2015 · To be precise light is an oscillating electric and magnetic field. Secondly, no light is not affected by other magnetic fields by external sources in vacuum. This is primarily due Principle of Superposition which states that fields themselves don't interact with each other. (In classical theory).

- Demystifying the connection between magnetic and electric fields
Light is an oscillating electric and magnetic field, so it is electrical and magnetic. Later: re the edit to your question, I think there are two issues. Firstly the interaction with electric charge and secondly the interaction with magnets. Light does not carry any charge itself, so it does not attract or repel charged particles like electrons.
Don’t confuse the properties of light with the properties of light’s interaction with the medium in which it is traveling. If light had a magnetic property, it would be affected by a magnetic field in a pseudo vacuum. It isn’t. If light had an electric property, it would be affected by an electric field in a pseudo vacuum. It isn’t.

Gamma rays, X-rays, ultraviolet light, visible light (the visible rainbow), infrared light, microwaves, and radio waves are all forms of light, also called electromagnetic radiation. Together, they make up the electromagnetic spectrum. (That’s right, the radio waves that carry music from the station to your radio, the microwaves that heat up your f...
Light behaves like a wave. You are probably familiar with waves: water waves that ripple across a pond, sound waves that vibrate air and ear drums, and seismic (earthquake) waves that cause the ground to shake. These are all mechanical waves—energy that propagates through matter, causing it to move up and down, back and forth, or side to side. Ligh...
Light also behaves like a particle. A particle of light is called a photon. Each individual photon has a very specific amount of energy (no more, no less), which corresponds to its wavelength. Blue photons carry more energy than red photons. Ultraviolet photons carry more energy than infrared photons. Sometimes photons are described as “packets of ...
Matter is the scientific catch-all word for stuff—anything that has mass and takes up space. Matter is made of microscopic particles called atoms. Atoms are made of even smaller, or subatomic, particles known as protons, neutrons, andelectrons. Atoms can combine to formmolecules. Solids, liquids, and gases are all forms of matter. Planets, stars, n...
As you may have gathered, light and matter are intricately linked. Matter gives off light. Every object emits, or gives off, light of one sort or another simply because of its temperature. Glowing objects like stars, galaxies, light bulbs, and lava are all sources of visible light. Cooler objects like planets, dust grains, rocks, trees, animals, an...
Sep 24, 2010 · Light is a wave of both electric and magnetic fields, but when these waves strike matter, the weaker effect of the magnetic component has been nearly impossible to detect directly. Now two groups have independently demonstrated that a tiny, metallic probe will interact strongly with the magnetic field of light waves trapped in a sort of semiconductor “box.”
spin 1/2 particle in an external magnetic field, because the spin can only be parallel or anti-parallel to the field, i.e. it has two energy levels and energy eigenstates [4]. The interaction of the two-level atom with the electric field of an electromagnetic wave is described by the Bloch equations. 6.1 The Two-Level Model

May 24, 2024 · Let's address a couple other elements of light as a wave. First, a medium is not needed, as electric and magnetic field can exist in a vacuum. The presence of a medium (such as air or water) does effect the electric and magnetic fields, because media are made up of atoms, which are composed of positive and negative electric charges. Because of ...
