Can magnetic force do work

WebAbstract. Standard lore holds that magnetic forces are incapable of doing mechanical work. More precisely, the claim is that whenever it appears that a magnetic force is doing work, the work is actually being done by another force, with the magnetic force serving only as an indirect mediator.

WebSep 12, 2024 · Define the magnetic dipole moment of 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. When current is passed through the loops, the magnetic field exerts torque on the loops, which rotates a shaft. WebFirst a magnetic field can do work on an elementary charged particle which has spin. So there's that. But you don't need to go all quantum. Classically, the magnetic field can do work on a magnetic dipole (think a tiny loop of current), as long as the field is not uniform. WebHowever, magnetic forces in a multiparticle system can rearrange the energy inside the system if these forces do as much negative work as they do positive work, resulting in a net work done of zero. Mathematical expression: The work done is W = ∫ F. → d l →, where F → is the force done on an object and d l → is the displacement. flint city wards
