This entity is crossed with a particle's velocity in the equation for the Lorentz force.
This entity is crossed with a particle's velocity in the equation for the Lorentz force. One law that gives the strength of this entity was modified to include the partial time derivative of the displacement field. The curl of this entity is equal to permeability of free space times the current density. Silver atoms were fired through an inhomogeneous version of this entity in the Stern-Gerlach experiment. This entity cannot be created by monopoles according to Gauss' law. Created by electrical currents, the strength of this entity is given by the Bios-Savart (Bee-oh Suh-var) law and Ampere's law. For 10 points, name this counterpart of the electric field, symbolized B.
