 Good morning physics students. It is Monday April 20th and we are continuing with Magnetics. As I've been looking through some of the practice problems you guys turned in for last Wednesday and Friday, you're definitely still having some issues with the directions. And that's kind of to be expected. It's really the first time this semester we've been working with three-dimensional things and it is a little bit more complicated to picture where everything's going. I'm going to do my best to try and make some additional videos to try and show you some things about these directions so that you can figure things out. But I also want you to go back and watch some of the videos I had already posted. So for example on Friday one of the extra videos that I had was the front side part two which dealt with the direction the magnetic field around that long straight wire. A lot of you had some answers that were different than what the correct answers were and that video really steps you through how I got the answers that I'm saying is correct. If you have questions please contact me but make sure that you are looking at the videos I already have posted, sending me questions when things don't make sense, and as I said I'm going to do my best to make some extra videos as well to help you see some of the directions and picture what's going on. I hope you guys have a good week this week. It's really the last full week of class. We'll be having a few classes next week and then final exams.
