Problem 7: The Lorentz force is the sum of the electric and magnetic forces acting upon a particle
with charge
9 and velocity
F = qË+qvxB
A velocity selector is a special arrangement of non-zero electric and magnetic fields that will allow
charged particles with a specified velocity to pass undeflected because the Lorentz force they
experience is zero. Charged particles with other velocities are turned aside. This is achieved as
follows:
• The three relevant vectors, v, Ē, and B are mutually perpendicular.
• The magnitudes of the vectors are chosen such that the magnitudes of the electric and magnetic
forces have equal magnitudes, or, equivalently, E = vB.
• The directions of the electric and magnetic fields are chosen such that the electric and magnetic
forces are oppositely directed.
The diagram to the right represents the directions of a uniform magnetic field and the velocity vector.
The charge of the particle is explicitly indicated as
+q> 0 or
-9 <0.
