Homework Help Overview

The discussion revolves around identifying the north and south poles of a magnet and the magnetic field produced by a current-carrying wire. Participants are exploring the characteristics of magnetic fields and their representations.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to apply the Right Hand Rule to determine the magnetic field direction but expresses confusion regarding the poles of the wire's magnetic field. Other participants question the nature of magnetic field lines and their implications for defining poles.

Discussion Status

Participants are actively engaging with the problem, with some suggesting that the question may have a trick element. There is a focus on understanding the behavior of magnetic field lines, particularly in relation to a wire, and the discussion is exploring different interpretations of how poles are defined.

Contextual Notes

There is an indication of a lack of knowledge regarding the properties of magnetic fields, which may be influencing the participants' ability to resolve the question. The discussion reflects uncertainty about the definitions and characteristics of magnetic poles in different contexts.

Homework Equations



Where are the north and south poles of this magnet?

Where are the north and south poles of the wire's magnetic field?

The Attempt at a Solution



I used the Right hand rule to determine the magnetic field of the wire, but I got confused when trying to find the north and south poles of the wire's magnetic field...

It's a trick question. Does that help?

Think about the lines of magnetic field from a wire carrying a current. Where do they begin and end?
 
So, no one can crack this?

I'm sure this is solvable, i just lack the knowledge abut the lines of a magnetic field..

Anyone?
 
Magnetic field lines are continuous, that is they link up with themselves. So even with a "normal" magnet the lines go right into and through the material. We say that the region where the lines exit the material is the north and where they enter is the south pole, but in the case of the wire the lines do not enter or leave it, they just encircle it, so there is no entry or exit point and thus no poles.
