... The loop remains in the plane of the page and never exits the magnetic field. Experiment III: With the magnetic field held constant, the loop is shrunk to one half its initial radius, always remaining within the plane of the page. Experiment IV: With the magnetic field held constant, the loop is rot ...

... Know the definition of magnetic flux, Equation 30-1. Know Faraday's law of induction, Equations 30-4 and 30-5. Be able to state Lenz's law: An induced current has a direction such that the magnetic field due to the current opposes the change in the magnetic flux that induces the current. The induced ...
