🟢 5: Th 4/18 - 📖 mass spectrometer

Today, you'll see a real life application of charges simultaneously in multiple fields we've already learned about. As practice, on a blank piece of paper, explain how a mass spectrometer works with a picture, force diagrams, and equations for all three regions. 

Then, we'll practice mass spectrometer problems by doing 📖 Mastering Physics "Ch 24 - mass spectrometer" problems: 3 tutorials plus #67, 69, 70, 32.  

Homework:  Finish these 📖 Mastering Physics problems above by Friday, April 19th at 10pm.  📖 Mastering Physics "Ch 24 - magnetic force on moving particles" due tonight.

Optional Extra Practice:  Mass Spectrometer Problems from AP Exam

🟩 5: F 4/19 - 📖 magnetic force on current carrying wire

Today, we'll look at what happens to a current carrying wire in a magnetic field. We'll learn the second right hand rule for a current carrying wire in a magnetic field, which is just a new perspective on the first one. We'll look at a couple of demonstrations to see how well you understand the first two right hand rules.

First watch my 10 minute video "Magnetic force on a current carrying wire."

Then, we'll practice F=IlB problems by doing 📖 Mastering Physics "Ch 24 - magnetic force on a current" problems: #33, 36, 37, 47, 48, 56, 58.  For #58, a linear mass density means a certan mass per length of wire.  You may assume that there is 1.00m of wire total for this problem.  

Homework:  Finish these 📖 Mastering Physics problems by Monday, April 22nd at 10pm.  📖 Mastering Physics "Ch 24 - mass spectrometer" problems due tonight.

Optional Extra Practice:  FYP: Electromagnetism #1-10 (ANSWERS)

💚 5: W 4/24 - 📖 current creates magnetic field

If you haven't finished the previous 📖 Mastering Physics "Ch 24 - magnetic force on a current" problems, start with that.  

Then, we'll learn how moving charges create magnetic fields. We'll learn the last two right hand rules.

First, watch my video on "Current Create Magnetic Fields." It's a rather long video, but you can probably speed up parts of it. I recap the most important parts of the embedded videos, but watching the embedded videos will really build your understanding.

Then, we'll practice with concepts of a magnetic field created by a current by doing 📖 Mastering Physics "Ch 24 - current creates magnetic field" conceptual and multiple choice problems: #C8, C9, C10, C13, C24, MC30, MC31, P68.  

Homework:  Finish these 📖 Mastering Physics  problems by Thursday, April 25th at 10pm.  Remember 📄Intro to Magnetism (PH) worksheet due at the beginning of next class - Thursday, April 25th.  QUIZ on all of magnetism up to this point (chapter 24 without the equations in 24.4 or 24.7) on Friday, April 26th.  

Optional Extra Practice:  FYP: Electromagnetism #1-10 (ANSWERS).  Optionally read parts of chapter 24.
