AT Cycle 25

🔴❗ 2: Th 2/8a, 🟡❗ 4: W 2/7, 🔵❗7: W 2/7 - circuits assessment

Circuits Unit Assessment TODAY!!!

Homework:  Review all of the magnetism topics you should have learned last year on my AT Magnetism Review page.  

🟥 2: Th 2/8b*, 🟨 4: Th 2/8*, 🟦 7: Th 2/8a - magnetism intro

Pd 2b & 4 go to sub study during F=ma contest.

In groups today, we'll try to compile a list of facts and equations that you should know about magnetism.  We'll collect all of the ideas and make sure you understand the following:

• Properties of permanent magnets (poles, domains) and magnetic fields (direction of magnetic field lines).  

• Magnetic field lines and 3-D notation.

• Magnitude and direction of force on a moving charged particle in a magnetic field.

• Magnitude and direction of force on a current carrying wire in a magnetic field.

• Direction of magnetic field created by a current-carrying wire.

• Direction of magnetic field created by a loop of wire or a solenoid.  

• Right hand rules associated with the concepts above.

Take notes on all of above and upload pictures of your notes to ✏️ Google Classroom assignment due Thursday at 10pm.  

With any time remaining, continue on to problems in the next post.  

Homework:  Make sure you have reviewed all of the magnetism topics you should have learned last year on my AT Magnetism Review page.  Upload PDF of your magnetism notes to ✏️ Google Classroom assignment due Thursday, February 8th at 10pm.  

❤️ 2: F 2/9, 💛 4: M 2/12a, 💙7: Th 2/8b - basic magnetism problems (1)

We'll start the period by testing our understanding of force on moving charged particles in magnetic fields with a couple of demonstrations. We'll discuss applications including the mass spectrometer.  We'll then apply our problem solving and collaboration skills by doing problems from AP problems for force by magnetic field.   (MC ans: CADEEACDA) 

Homework:  Work on above problems and upload FRQ solutions to ✏️ Google Classroom assignment by Tuesday, February 13th at 10pm.  

📕 2: M 2/12, 📒 4: M 2/12b, 📘7: F 2/9 - basic magnetism problems (2)

This hour, we'll continue to apply our problem solving and collaboration skills by doing problems from AP problems for force by magnetic field.   (MC ans: CADEEACDA) 

At the end of class, we will review how we know the direction of the magnetic field created by a wire or solenoid.  Then, we'll learn to quantify the magnetic field with the Law of Biot-Savart.  (This law is the magnetic field analog to the superposition integral for electric field E=∫dE .)  

Homework:  QUIZ on Magnetism Review on Wednesday, February 14th.  Finish all of the problems and upload FRQ solutions from AP problems for force by magnetic field to ✏️ Google Classroom assignment by Tuesday, February 13th at 10pm.  Watch the following video on how to use the Biot-Savart Law:
