HomeworkFaraday's Law ✏️ Google Classroom assignment due Tuesday at 10pm.  Quiz on Induction Review on Monday, March 13th.  Watch the following video on the emf induced in a moving conductor.  (If you need more information on how to derive the formula ε = BLv, check your textbook Section 30-2 or look at the picture of the excerpt from Giancoli below the video.):

Here are a couple other videos from last year that you may want to review on motional emf:

BY CLASS TIME ON TUESDAY, MARCH 21stWatch the following videos on the electric field induced by a changing magnetic field.  Before watching though, think about the following situation.  So we know by F = qv x B that a MOVING charge in a magnetic field feels on a force and can be made to move.  Let's say we have a loop sitting in a constant magnetic field at first.  The charges sitting in the loop are not moving - even though these charges are in a magnetic field, there are no forces on the charges because their velocity is zero.  But as soon as we try to change that magnetic field, all of a sudden, the charges start to move - a current is induced.  That implies that there is a FORCE on those charges causing them to accelerate from REST.  Where does that force come from?  Can it be a magnetic force dictated by F = qv x B?  If not, what kind of force is it?  Seriously think about these questions!  Now watch the videos.
