Magnetic Force Definition Formula Examples Facts Britannica We've all played with magnets before watching them attract or repel via magnetic force. in this video, i make the bold claim that magnetic force doesn't actually exist. it's an. What we call a magnetic force is nothing more than an illusion, a consequence of special relativity as charged particles are moving at near speed of light relative to other charged particles.
Magnetic Force Definition Formula Examples Facts Britannica As this would obviously contradict the definition of a force, it is postulated that the magnetic force does not exist as a separate physical force, but merely as part of an 'electromagnetic' force composed of an electric and magnetic part (which is usually written then as f l =q. (e v c×b)). While this force involves electric charge, it clearly is not electrical in nature. that is, it is altogether different from the coulomb force. we therefore give it a different name. we call it the magnetic force. like the electric force, we will explain it in terms of a vector field. No, the direction of the magnetic force consistently changes since the direction of the particle's velocity continuously changes, and the direction of the magnetic force is dependent on the direction of the velocity of the electron. Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges. the magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.

The discussion revolves around the concept of magnetic forces and their work on charged particles, specifically examining a proof from "introduction to electrodynamics" by david j. griffiths that claims magnetic forces do no work. The magnetic force on a magnet by a current carrying wire is indistinguishable from the magnetic force of another magnet. therefore, to understand the magnetic force of a current carrying wire, we say that electric current has magnetic field just like the magnetic field of other magnets. An ordinary bar magnet consists of many permanent dipoles whose interaction is the source of the magnetic force. it is possible to quantify this force by adding individual interactions. In other words, one magnet does not need to touch another magnet to feel its presence. scientists make sense of this ‘force at a distance’ by attributing it to the existence of an invisible field that surrounds the magnet.
