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
In physics (particularly in electromagnetism) the Lorentz force is the combination of electric and magnetic force on a point charge due to electromagnetic fields. A particle of charge q moving with velocity v in the presence of an electric field E and a magnetic field B experiences a force. (in SI units).
The magnetic force microscope (MFM) is a variety of atomic force microscope, where a sharp magnetized tip scans a magnetic sample; the tip-sample magnetic interactions are detected and used to reconstruct the magnetic structure of the sample surface.
Magnetism could be said to be an electrodynamic force, but it rarely is. The combination of electric and magnetic forces on a charged object is known as the Lorentz force.
magnetism: Magnetic forces. phenomenon associated with magnetic fields, which arise from the motion of electric charges. This motion can take many forms.
The magnetic force of a magnet is in inverse proportion to its coercive force (resistance to a magnetic field on the outside), and magnetic force weakens as the temperature rises.
The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature.
Stationary charges interact through the electric force. Charges in motion constitute currents. When currents are present, magnetic forces also act.
There is no magnetic force on stationary charged particles, and the force. on a moving particle is perpendicular to the particle’s velocity.
