A Stern Gerlach Experiment

In-class group activity 10: A Stern Gerlach Experiment

Use an on-line simulation from the University of Colorado PhET group to carry out a Stern-Gerlach Experiment.  
Link to the simulation http://phet.colorado.edu/en/simulation/stern-gerlach.  Click "Run Now!".

Open a Microsoft Word document to keep a log of your procedures, results and discussions.

You can perform experiments with one, two or three magnets.  If you choose “up” to open the exit hole for the spin-up particles and block the hole for the spin-down particles, you have a spin filter as described in the notes.
