www.phys.hawaii.eduElectric/Magnetic Velocity Selector A charged particle enters a region with perpendicular electric and magnetic fields. The electric and magnetic forces will cancel if the velocity is just right. Particles with this velocity will go through undeflected. Others will be deflected.

Lecture 5 Motion of a charged particle in a magnetic field
www.tcm.phy.cam.ac.ukClassically, in electric and magnetic field, particles experience a Lorentz force: F = q (E + v × B) q denotes charge (notation: q = −e for electron). Velocity-dependent force qv × B very different from that derived from scalar potential, and programme for transferring from classical to quantum mechanics has to be carried out with more care.
Chapter 2 Motion of Charged Particles in Fields
ocw.mit.eduMotion of Charged Particles in Fields Plasmas are complicated because motions of electrons and ions are determined by the electric and magnetic fields but also change the fields by the currents they carry. For now we shall ignore the second part of the problem and assume that Fields are Prescribed.

Since fields interact with particles, it be-came clear by the late 1920s that an internally coherent account of nature must incorporate quantum concepts for fields as well as for particles.

Electric and Magnetic Forces
web.mit.eduquantity H,andB is called the magnetic induction.) In terms of the field, the magnetic force on i dl is Equation (3.5) involves the vector cross product. The force is perpendicular to both the current element and magnetic field vector. An expression for the total electric and magnetic forces on a single particle is required to treat beam dynamics.
