Magnetic poles(repulsion+attraction)

  1. What makes a magnetic pole attract another, while, the other kind repel each other?

    Superweirdo, rather than shooting a hundred basic questions at the forums, you would be better served to try and learn the subject matter on your own and come here with specific doubts regarding points that you are unclear about. That would also be in the best interest of the forums, in my opinion.

    For instance, you must first understand broadly how a magnet works, before you start wondering about why it behaves in a certain way. I could tell you that the dipole-dipole interaction energy has a maximum for one orientation and a minimum for the other, but that would help in no way unless you know how to calculate such a thing.

    From all the other threads I've read, I don't get the impression that you are actually learning anything...just picking up a few disconnected tidbits that will sooner than later leave your head for lack of a unified comprehension.

    What we could do well, however, is point you to learning resources that will help build such a comprehension.

  4. Actually to tell you the truth, this forum has taught me a lot of things, I am in in AP physics right now and I am grasping all the material. The only thing I didn't get here is the the one about how an atom decays b/c I need to review that stuff, I also know that too. But I guess for this question, I better get a deep knowledge in this category instead of asking this question. Can you perhaps direct to a link?

    Something along the lines of : http://www.coolmagnetman.com/maghow.htm

    followed by or in conjunction with an understanding of how dipoles create and interact with fields. There's a brief discussion of results in the early part of this article: http://en.wikipedia.org/wiki/Dipole

    The best way to learn this stuff, however, is from a standard physics text that handles electricity and magnetism (eg: Resnick & Halliday)
     
  6. Superweirdo,

    Did you know that magnetism is a 100% relativistic effect? That was the most interesting thing I learned about it.
