In an electromagnetic field, the force on a charged particle is given by F = q(E + v × B). If the charge of the particle is 2 C, the electric field E is 3 N/C, the velocity v is 4 m/s, and the magnetic field B is 1 T, what is the force?
on a charged particle in magnetic fields superimposed on the static Schwarzschild background and show the possible existence of bound orbits for particles in the field of ultra compact objects at distances r 3 m wherein the Lorentz force counterbalances both the gravitational and centrifugal forces....
Magnetic force is always perpendicular to velocity, so that it does no work on the charged particle. The particle’s kinetic energy and speed thus remain constant. The direction of motion is affected, but not the speed. This is typical of uniform circular motion. The ...
In summary, a B-field, or magnetic field, is a region in space where magnetic forces act on charged particles. The force on a particle in a B-field can be calculated using the equation F = qvB sinθ, where q is the charge of the particle, v is its velocity, B is the strength ...

In fact, this is how we define the magnetic field strength B—in terms of the force on a charged particle moving in a magnetic field. The SI unit for magnetic field strength B is called the tesla (T) after the eccentric but brilliant inventor Nikola Tesla (1856–1943)...
