### 🔴 2: W 2/28a, 🟡 4: T 2/27, 🔵7: T 2/27 - mass spectrometer

Today, you'll see a real life application of charges simultaneously in multiple fields we've already learned about.

Then, as a final review, we'll do some practice with a mass spectrometerMake sure you enter YOUR first and last name in the name field on the "enter answers" tab.

HomeworkUpload your "calculations correct" screenshot to ✏️ Google Classroom by Wednesday at 10pm.  Only screenshots with YOUR first and last name will be accepted for credit.  Study for Unit Assessment on all of Magnetism next class - Wednesday, February 28th.

### 🟥❗ 2: W 2/28b, 🟨❗ 4: W 2/28, 🟦❗ 7: W 2/28a - magnetism assessment

Unit Assessment on all of Magnetism Today!

Homework:  Make sure you have reviewed all of the induction topics you should have learned last year on my AT Induction Review page.

### ❤️ 2: Th 2/29, 💛 4: F 3/1a, 💙7: W 2/28b - induction review

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

Take notes on all of above and upload pictures of your notes to ✏️ Google Classroom assignment.

Homework:  Make sure you have reviewed all of the induction topics you should have learned last year on my AT Induction Review page.  Upload pictures of your induction notes to ✏️ Google Classroom assignment due Friday at 10pm.

### 📕 2: F 3/1, 📒 4: F 3/1b, 📘7: Th 2/29 - Lenz's Law  & Faraday's Law Review (1)

Today, we'll review Lenz's Law (presentation).  We'll briefly discuss ways of inducing a current in a loop of wire.  We'll review Lenz's Law which states, "An induced emf gives rise to a current whose magnetic field opposes the original change in flux."  We'll see how we might use this concept to generate electricity to power a lightbulb.  Practice at least one from each page on the Lenz's Law Practice page below.

Then, we'll explore Faraday's Law with simulations and video demonstrations. Record your observations for each simulation/demonstration  in ✏️ Google Classroom by Sunday at 10pm.

INVESTIGATION 1:

What happens when a magnet moves through a coil in which a current can flow?

Move the magnet at a relatively constant frequency back and forth through the coil.  The voltage displayed is proportional to the current flowing in the coil.  Watch the reading of the voltmeter.  What happens
