We are given the charge, its velocity, and the magnetic field strength and direction. We can thus use the equation F = qvB sin θ to find the force. Solution The magnetic force is F = qvB sin θ We see that sin θ = 1, since the angle between the velocity and ...
A theoretical analysis of magnetic field effects on the Friedel-Kohn "wiggle" contribution to shielding by a quantum plasma is carried out here for conditions of intermediate magnetic field strength ( E F > ω c > kT). In this case, magnetic field quantum corrections to the Friedel-Kohn "...
