Can a magnetic field do work
WebThe magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other. From this point of view, the magnetic force F on the second particle is proportional to its charge q2, the magnitude. magnetic force, attraction or repulsion that arises between electrically charged ... WebSep 5, 2024 · Key Takeaways: How Magnets Work. Magnetism is a physical phenomenon by which a substance is attracted or repelled by a magnetic field. The two sources of magnetism are electric current and spin magnetic moments of elementary particles (primarily electrons). A strong magnetic field is produced when the electron magnetic …
