Week 13
modified 20-Apr-2018 at 12:23PM by Thomas Walsh

There is an error in the Canvas MC scores (25 total instead of 10), and a bug that prevents the Quiz 4 total showing up I will fix all this later. Not to worry.

Week 10
modified 28-Mar-2018 at 10:30AM by Thomas Walsh

Lectures this week are mostly on atomic and nuclear dipoles and their connection to magnetic imaging. Book section 19.5 is on magnetic dipoles, and SK 20.9 is connected to magnetism in iron. SK 29.6-29.13 is on NMR and magnetic imaging.

Toward the end of the week we move on to electromagnetic waves and waves more generally. Read Chapter 21 on waves.

The lab this week is Lab 5, Problems 1, 2 & 5; you should do the warmups for both before lab.

You will be assigned a lab report this week, due next week.

Last week's Quiz 3 average, excluding 0 scores, was 75%

Week 9
modified 27-Mar-2018 at 4:14PM by Thomas Walsh

This is the week after spring break.

There is a quiz on Friday. The quiz will be in Bruininks Hall 230. It will cover the material since the last quiz (weeks 6, 7, 8). Same format as the first two quizzes. The current week's material will only appear in the multiple choice problems, if then. There will be no word problem on cell electricity.

This week we are on the consequences of Faraday's discovery of induction. Some possibly useful sections in SK are in Chapter 20, sections 1-4, 6-8, 10-11

This week we do Lab V, problems 7 and 8; be sure to do the warmups in your lab notebook.

Week 8
modified 7-Mar-2018 at 11:41AM by Thomas Walsh

This week is on magnetic fields, currents and force, including electric motors. At the end of the week we begin discussion of Faraday's Law. The subjects are also covered in SK, chapter 19, thru 19.8. Also read 19.11, 19.12. By the end of the week you should have started reading Chapter 20.

This week we will be doing Lab 2, Problems 6, 7. Do the warmup questions in your lab notebook in advance.

There is no lecture Friday, March 9

There will be no office hours this week

Week 7
modified 2-Mar-2018 at 11:17AM by Thomas Walsh

This week we finish electricity and cells Monday (SK Chapter 18). We then move on to magnetism. You should start reading Chapter 19. The part on circular orbits in a constant uniform magnetic field is important.

The week's lab problems are Lab 2, problems 3 and 4, both qualitative. Write out the answers to the warmup questions in your own words.

Your TA will assign a lab report due next week, (due week 8).

The homework this week is on cell electricity.

Last week's quiz 2 average was 74%

Week 6
modified 21-Feb-2018 at 3:28PM by Thomas Walsh

There is a quiz Friday on the material of weeks 3, 4 and 5. The quiz will be in Bruininks Hall 230 There is stuff on currents (simple circuits with R's and/or C's) but also including the RC circuits you have seen already. Use the sample quiz for guidance. The format will be the same as for Quiz 1-you can use a 3x5 card of notes, writing implements and a calculator.

The lectures this week will begin with tail material of currents and then begin to cover the electrical properties of cells.

This week's lab is Lab 3 Problems #6 and #7. This time, write up warmups 1-7 for Problem #6 and warmups 1-4 for Problem #7

This week's homework is on material that we have already mostly covered.

Week 5
modified 16-Feb-2018 at 1:02PM by Thomas Walsh

You have a lab report due this week.

We are mostly on batteries, currents and circuits this week For related book material, see SK sections 17.1 thru 17.5. You may want to read thru 17.8.

Lab this week is Lab 3, Problem 1 and Problem 2. You might want to look at review questions 16.89 thru 16.93 and their answers. (Also note that the lab suggests reading sections 17.7 and 18.4, both of which we will get to in more detail later.) In your lab notebook write up in advance warmup questions 1, 2 and 3. Your TA will help you understand the circuits involved.

Week 4
modified 9-Feb-2018 at 2:11PM by Thomas Walsh

Topics this week are electric field energy and potential. Relevant book sections are 16.9, 16.10 and 16.11.

The lab this week is Lab 4, Problems 4.5 and 4.6; write up the warmup problems 1, 5 and 6 to Problem 4.5; writeup warmups 7 and 8 for Problem 4.6

Your TA will assign a lab report, due next week. Remember to submit two things: the assigned report plus a photocopy of your lab notebook pages for Lab 4

The Quiz 1 average seems not to be on Canvas. I got 63% for the overall average. (This is wrong. Once I remove the students who did not take the quiz, the average was 69%)

Week 3
modified 31-Jan-2018 at 1:01PM by Thomas Walsh

We have a quiz Friday, class hour. The quiz will be in Bruininks Hall 230. Check the UMN map.

There will be 5 multiple choice problems (answers on bubble sheets) and two word problems to be done on the provided quiz sheets. You may use both sides of a 3x5 card of your notes - whatever you judge useful on the quiz - writing implements and a calculator. The quiz will cover material of Weeks 1 and 2.

This week we are on electric field flux and Gauss' Law. Some useful sections in the book for background are 16.3 (fields from charges), 16.5 (electric potential), 16.6 (equipotentials) . (We won't actually cover electric potential and equipotentials this week, but it is a good idea to look at those sections anyway.) We will mainly cover Gauss' Law, SK (book) sections 16.11 and 16.12. At the end of the week we will deal with charges accelerated by electric fields.

In lab, you will do experiments 4.1 and 4.2 (Problems 1 and 2.) in Lab 4, Electric Fields and Potential. Before lab, you should write out warmups 1 and 2 for Problem 1 and warmups 1,2 and 3 for Problem 2 in your lab notebook. Your TA will check your lab notebook at the beginning of lab.

Homework #3 (remember, your TA will check it off Thursday) is SK Review Questions Q16-1 – Q16-6 (page 411) and SK 16-79, 16-94, 16-97 (pages 418, 425) There are also five additional problems (see the"Additional Homework Problems") Your TA will check your homework notebook Thursday.

Notice on the sample quiz that I will in future expect you to be able to use what you learned in 1201 about force, work and velocity.

Week 2
modified 26-Jan-2018 at 11:28AM by Thomas Walsh

This week we cover electric fields and field lines for configurations of charges--see SK 16.1, 16.2, 16.3, 16.4 and 16.10. (This refers to sections in the Sternheim and Kane book, "SK".) Also, look at 16.12 - Flux and Gauss' Law that we will touch on Friday.

For some background on atoms--see SK 27.3,27.4, 28.5

For the Thursday group meeting, you should read ahead a bit, on the Electric Field of a uniformly charged plate. Also make sure that you understand the Electric Field of a uniformly thin charged rod.

This week we have an orientation lab. The TAs should discuss what is expected of you: what a good lab notebook looks like and what a good lab report looks like. You will be taking a survey quiz, hosted on Canvas. So please have at least one person in your group bring a laptop or iPad.

Homework #2 is due Thursday and will be checked off by your TA. Remember to keep a separate homework notebook.

SK Chapter 16 problems 9, 13, 16, 22 and 45 (page 412+)
SK Chapter 16 problems 64 and 69 (page 416)

The solution manual for SK is posted at the class material link, but you should first try to do the problems before checking the solutions.

Week 1
modified 24-Jan-2018 at 11:16AM by Thomas Walsh

There is no lab the first week There is an orientation lab meeting the second week. Please download the lab manual, you will use it!

However, Thursday group problem sessions will meet the first week. You have to check your registration materials for the Thursday room assignments.

Office hours in the tutoring area will be posted later.

Please look thru the "Supplementary Material" There is useful stuff posted there.

The first week you should read the book sections on Coulomb's law, SK 16.1 (i.e. the text, Chapter 16, section 1) and also 16.2 on the electric field, before Thursday. I assume that you will read the SK section on the electric field, which we will cover in more detail next Monday.

There is homework for this week, it is the four book problems SK 16.1, 16.3, 16.4, 16.5 at the end of the chapter; read the syllabus--you need to keep a homework notebook, checked on Thursday.

In future weeks, I may post a few suggested problems not due Thursday. Wednesdays I post the Thursday group problem. Also, note that the solutions to the SK book problems are now posted in the Supplementary Material section
