Homework Help Overview
The discussion revolves around the application of Ampere's Law in calculating the magnetic field (B) related to a current-carrying wire and its behavior within a fixed rectangular area. Participants are exploring the implications of the magnetic field's constancy and its dependence on distance from the wire.
Discussion Character
- Conceptual clarification, Assumption checking
Approaches and Questions Raised
- Participants are questioning the assumptions regarding the constancy of the magnetic field within the rectangle and its dependence on distance from the wire. There is a focus on understanding the relationship between the magnetic field and the geometry of the setup.
Discussion Status
The discussion is active, with participants raising questions about the assumptions made in the original poster's calculations. Some guidance has been offered regarding the behavior of the magnetic field in relation to distance from the wire, but no consensus has been reached.
Contextual Notes
There is an acknowledgment that the rectangle is fixed to the ground, and the magnetic field's direction changes, which may influence the calculations being discussed.

Do you mean that B is constant inside the rectangle?

It's a given that the rectangle is fixed to the ground..
So apart from the fact that the magnetic field in it changes direction all the time, B's size is constant
So apart from the fact that the magnetic field in it changes direction all the time, B's size is constant

So you say that the magnetic field of a current carrying wire does not depend on the distance from the wire?

For a long straight wire, B is proportional to 1/r.
