HP Cycle 38

Then, we'll take a look at a moving bar in a magnetic field which will produce a motional emf.  Using what we learned last time about Faraday's Law, we'll derive an equation that can help you understand this relationship.  (Faraday's Law, ε = -N ΔΦ/Δt and I = ε/R (Ohm's Law)).  Watch the video.  

Then, we'll practice motional emf problems by doing problem solving.

Homework:  Unit Assessment on all of Magnetism & Induction TBD!

Optional Extra Practice:  📖 Mastering Physics "Ch 25 - motional emf" problems #C3, C18, 4, 7, 62, 65.  Read any sections in chapter 25.1-3 that seem unclear.  Then do at least #11-12 of page 2 of FYP: Electromagnetism  (ANSWERS). The video will help you with these two problems.
