AT Cycle 25

🔴❗2: W 2/18, 🟡❗4: W 2/18a, 🔵❗7: W 2/18 - Ampere's Laws AP problems (1)

Today, we'll start by finishing any problems that you didn't finish from the textbook.  Then, we'll use what we've learned about Ampere's Law to solve some AP problems.  

    Required 1:  2000E3, 1993E1, 1979E2

Homework:  Finish all Ampere's Law AP problems above.  Unit Assessment on all of Magnetism Tuesday, February 24th.  Review induction concepts for next unit by watching videos on my AT Induction Review page.  Maybe re-watch the Mass Spectrometer video as review for the test.  

🟥 2: Th 2/19a, 🟨 4: W 2/18b, 🟦 7: Th 2/19a - Ampere's Laws AP problems (2)

Today, we'll finish any problems that you didn't finish from previous posts.  Then, we'll use what we've learned about Ampere's Law to solve some AP problems.  

    Required 1:  2000E3, 1993E1, 1979E2 (assigned in previous post)
    Required 2: 1983E3*, 1988E3a, multiple choice

    * Add the following part to the 1983E3 problem: 
(c.) (i.) Find an expression for the force per unit length between the two wires.  (ii.)  Is this force attractive or repulsive?
        ANSWER: (c.)(i.)  F/ℓ = μ0 I1 I2 / (4πa).  (ii.) attractive

    Multiple Choice Answers:  19-E, 47-D, 68-C, 65-D, 50-E, 42-E
