Day 103: Starting Restoring Force

We finished magnetism today. The change in the magnetic flux can be hard to see, so I made skid some flash cards after school today. We had pictures of various situations on one set and descriptions of possible changes to the flux on the other set. One from Set A, one from Set B, then go! What is the induced current?

We then moved to a mass on a spring. The graphs were pretty, and we could explain them well.
