- For this activity, students are placed into small groups and asked to use the SPINS program to find how a magnet in the program affects the state of an incoming particle.
- Students will calculate the probability that the $\vert \psi \rangle$ made by the magnet will be measured in the $\vert \phi \rangle$ state, where $\phi$ can be any one of spin-up or spin-down states with x,y, or z-orientation.
