How Hard Is Physics II: Electricity, And Magnetism?

Click For Summary

Discussion Overview

The discussion revolves around the perceived difficulty of Physics II, specifically focusing on Electricity and Magnetism (E&M), from the perspective of students who have taken or are currently taking the course. Participants share their experiences, concerns, and advice regarding the mathematical and conceptual challenges of the class.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification
  • Homework-related

Main Points Raised

  • One participant expresses concern about the difficulty of the class, noting their background in calculus and previous physics courses.
  • Another participant describes the class as conceptually tough but mentions that the math involved is not particularly advanced, primarily involving basic integration techniques.
  • A different participant reports finishing the class with an A, attributing the struggles of others to a lack of effort rather than the material itself.
  • There is a question raised about whether the course is an honors or regular version, indicating that this distinction may affect the difficulty level.
  • Some participants suggest that E&M is one of the hardest parts of the core physics curriculum, but they also note that the introductory level is generally manageable.
  • One participant warns that weaknesses in trigonometry or calculus could significantly hinder performance in the course.
  • Another participant shares a positive experience, mentioning that the class included topics like relativity, which they found enjoyable.
  • A participant references a friend's experience in an honors EM class that began with relativity, suggesting that such a structure could enhance understanding and engagement.
  • One participant finds the course challenging but believes it is not drastically different from previous physics classes, emphasizing the importance of practice.

Areas of Agreement / Disagreement

Participants express a range of opinions about the difficulty of the course, with some finding it manageable and others considering it challenging. There is no consensus on whether the course is inherently difficult, as experiences vary widely based on individual backgrounds and the specific course format.

Contextual Notes

Participants mention varying experiences with the course based on their mathematical preparedness and the distinction between honors and regular classes. Some express that the level of effort put into the course significantly impacts outcomes.

So I am taking Physics II this fall semester. I am an engineering major, and I am currently split between mechanical, and civil. My questions is how hard will the class be for me? I have already done the three semesters of calculus including a vector calculus extension. I got an A in calc III, but a B in calc II because it was my first semester of college. Other than that I have gotten all A's. The other physics classes I have taken so far are Physics I, and Statics? I feel like I am worrying about nothing, but that may just be me. Any advice for the class in general?

It's a conceptually tough class, I am taking it now. The math isn't hard, at most trigonometric substitution is used as far as advanced methods of integration are considered. It's mostly just natural logs, exponentials, etc. Just learn the concepts really well
 
Not too bad, just finished the class. I got an A. Most of the people in my class failed but I could tell it was because they didn't put in the work. The math isn't hard, just integrating as mentioned, but the concepts are important. The main thing is make sure you do practice problems over and over again.
 
Is this going to be honors physics 2 or regular physics 2? It makes a quite a difference (depending on your university anyways).
 
Not terribly difficult, actually it was pretty interesting
 
E&M's the hardest part of the core physics curriculum, in my opinion, and that's true for the intro level, the advanced undergrad level, and the grad. level.

That said, the intro level shouldn't be too difficult. They usually try to keep the problems simple enough that basic integration techniques are sufficient.
 
Any weaknesses in your trigonometry or vectors and calculus will klobber you in the fundamental E&M intro physics course. This was one the the very worst courses for me.
 
I loved that class, we even got to relativity in the end.
 
One of my friends took honors EM at UPenn. They used Purcell-Morin and he said the instructor structured the class so that they started with relativity. I would say this is the best model for an EM class, certainly one that would allow for a more fruitful and deeper understanding of EM. So before you decide to take the regular class, see if your school offers an honors EM class of a similar nature, or just an honors EM class period. You have the math background already so you might find an honors version to be much more rewarding. Typical regular intro physics 2 classes can be quite dull and lacking heavily in math, if that matters to you.

Personally, I found it challenging. You should really know what you're doing in physics I with vectors and trig as mentioned above. But yeah, if you loved your other physics class, it really isn't that much different in my opinion. Just practice a lot and make sure you know how to approach problems.
