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
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.
In physics, particularly in electromagnetism, the Lorentz force is the combination of electric and magnetic force on a point charge due to electromagnetic fields. If a particle of charge q moves with velocity v in the presence of an electric field E and a magnetic field B, then it will experience a force...
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.

There is no magnetic force on stationary charged particles, and the force. on a moving particle is perpendicular to the particle’s velocity.
We could observe the magnetic force in space around a magnet which helps in moving these magnetic substances. The magnetism is said to be induced by the magnetic field of the permanent...
Note that the magnetic force depends on the velocity, so there will be some particular velocity where the electric force qE and the magnetic force qvB are equal and opposite.
Solution: The electric and magnetic force, F = q(E + v × B) provides the centripetal force required for a circular orbit.: Consider the geometry shown in the figure on the right.
