Light does not carry any charge itself, so it does not attract or repel charged particles like electrons. Instead light is an oscillating electric and magnetic field. If you take an electron and put it in a static electric field (e.g. around a Van de Graaff Generator) then the electron feels a force due to the field and will move.

Mar 6, 2015 · Light is an electromagnetic wave. 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).
Here's how to think of it: Sources of electric force are (1) electric charges and (2) moving magnetic fields. Sources of magnetic force are (1) moving electric fields. This asymmetry - that there are no "magnetic charges" that can be sources - is the reason that we draw a distinction between electricity and magnetism. $\endgroup$ –
Dec 28, 2020 · Electric fields and magnetic fields work the same way, except they apply forces dependent on an object's charge and magnetic moment respectively instead of its mass. The electric field results directly from the existence of charges, just as the gravitational field results directly from mass.
The electric field is defined as the force per unit charge on a test charge, and the strength of the force is related to the electric constant, ε 0. Magnetic field lines are continuous, having no beginning or end. No magnetic monopoles are known to exist. The strength of the magnetic force is related to the magnetic constant, μ 0. A changing ...
Oct 24, 2024 · Once generated, it is self-propagating because a time-varying electric field produces a time-varying magnetic field, and vice versa. Electromagnetic radiation travels through space by itself. The belief in the existence of an ether medium, however, was at the time of Maxwell as strong as at the time of Plato and Aristotle.
We are studying two separate effects here that interact closely: A current-carrying wire generates a magnetic field and the magnetic field exerts a force on the wire. 11.6: Force and Torque on a Current Loop Motors are the most common application of magnetic force on current-carrying wires. Motors contain loops of wire in a magnetic field.
