Magnetic forces


The magnetic field B is defined from the Lorentz Force Law, and specifically from the magnetic force on a moving charge: The implications of this expression include

Electromagnetism - Wikipedia


Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles. The electromagnetic force usually exhibits electromagnetic fields such as electric fields, magnetic fields...

Force-free magnetic field - Wikipedia, the free encyclopedia


A force-free magnetic field is a magnetic field that arises when the plasma pressure is so small, relative to the magnetic pressure, that the plasma pressure may be ignored, and so only the magnetic pressure is considered.

Magnetism: fields and forces


magnet, magnetic field, magnetic field line, magnetic field strength, tesla, north pole

Electric Field vs Magnetic Field - Difference and Comparison | Diffen


The area around a magnet within which magnetic force is exerted, is called a magnetic field. It is produced by moving electric charges.

Physics Homework Help: Magnetic Fields, Forces


The direction of the field is by definition the direction of the force on the north end of a magnet. Since most texts contain diagrams of magnetic fields they will not be reproduced here.

Magnetic Field and Magnetic Forces

Chapter 27 | Magnetic field lines are not lines of force


• Magnets and the forces they exert on each other • Force that a magnetic field exerts on a moving charge • Magnetic field lines with electric field lines • Motion of a charged particle in a magnetic...

Magnetic field - New World Encyclopedia | Direction of force


A magnet will move to maximize the magnetic field in the direction of its magnetic moment.

Forces on currents in magnetic fields


A magnetic field will exert a force on a single moving charge, so it follows that it will also exert a force on a current, which is a collection of moving charges.
