The Magnetic Deflection

In this experiment we will observe magnetic forces on an electron beam. First we will use a magnet to set up a magnetic field that will exert a force on one electric current, the electron beam. Then we will use a second current in a solenoid to set up a magnetic field to exert a force on the electron beam. We think of the magnet or the second current in the solenoid as establishing a magnetic field in space. The electron beam (or first current) then moves through this field and experiences a magnetic force.
