In the Stern-Gerlach experiment , they used silver ions with a an unpaired electron in the outer shell...The typical result from passing the silver ions through a Non-uniform magnetic field is to separate spatially the bean into two types of "spin"...In other words the non-uniform B filed cause a force component to act in the direction of the field gradient. But didn't the particles have a net charge?? If so, why didn't the Magnetic field cause the usual Lorentz force to cause typical curvature in the beam trajectory perpendicular to the B field lines??? Here's the picture of the exper. set-up: https://www.google.com/search?q=ste...=dT3HV8iJM4TzmQHXzYzIDA#imgrc=sFRcsxTcpjBfCM: Thanks.
