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....
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 of the magnetic field, and θ is the angle between the velocity and the magnetic field. ...
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?
magnet′ic field′ n. 1. a region of space near a magnet, electric current, or moving charged particle in which a magnetic force acts on any other magnet, electric current, or moving charged particle. 2. a vector quantity defined by the force exerted on a given object at each point...
(2002), we perform parametric studies on the effect of particle size, shape and position in a non-uniform magnetic field. We conclude the examples by investigating the interaction of two particles immersed into a magnetic field. This remainder of the manuscript is structured as follows: In ...
Describe the effects of a magnetic field on a moving charge. Calculate the radius of curvature of the path of a charge that is moving in a magnetic field. Magnetic force can cause a charged particle to move in a circular or spiral path. Cosmic rays are energetic c...
