π΄ 1: W* 3/10, π‘ 3: W* 3/10a Faraday's Law Problems
Daily check-in: magnetic flux with calculus
Today, you'll finish working on some problems from the textbook Chapter 30 involving Faraday's Law:
Required: Ch 30 Questions #11, 12, Problems #2, 3, 7, 12, 13, 17, 18, 26, 96
Enrichment 26, 27, 28
With any time remaining, make sure you have watched the videos below and then start textbook problems in the next post.
Homework: Watch the following video on the emf induced in a moving conductor. (If you need more information on how to derive the formula Ξ΅ = 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:
π₯ 1: Th 3/11, π¨ 3: W* 3/10b motional emf
Daily check-in: motional emf
Today, after the check-in, we'll work on some problems from the textbook Chapter 30 involving motional emf:
Required: 33, 34, 35
Homework: Quiz on Induction Review on Tuesday, March 16th. Finish any of the above problems.
β€οΈ 1: F 3/12a, π 3: F 3/12 β©οΈ Pivot induction lab
Today, we'll start a lab in β©οΈ Pivot Interactives called "Electromagnetic Induction." In this lab, we'll explore Faraday's Law: the relationship between the rate of change of magnetic flux and the electromotive force (emf). We'll apply Faraday's Law to a coil moving in a magnetic gap, and use the measurements to determine the value of the B field in the gap. Then, we'll analyze a second scenario where we use Lorentz force to determine the B field in the gap. Finally, we'll compare the values for the B field using these two methods. Lab due Tuesday at 10pm.
π 1: F 3/12b, π 3: M 3/15 β©οΈ Pivot induction lab
Today, we'll continue the lab in β©οΈ Pivot Interactives called "Electromagnetic Induction." In this lab, we'll explore Faraday's Law: the relationship between the rate of change of magnetic flux and the electromotive force (emf). We'll apply Faraday's Law to a coil moving in a magnetic gap, and use the measurements to determine the value of the B field in the gap. Then, we'll analyze a second scenario where we use Lorentz force to determine the B field in the gap. Finally, we'll compare the values for the B field using these two methods.
Homework; Lab due Tuesday at 10pm. Quiz on Induction Review Tuesday, March 16th - Faraday's Law & Lenz's Law. Quiz includes any information on the Induction Review page which includes Lenz's Law, simple Faraday's Law problems, and simple motional emf problems.
