Homework Help Overview

The discussion revolves around calculating the magnetic field of a current loop, specifically focusing on the magnetic field values at certain distances from the coil. Participants are exploring the implications of their calculations and the definitions involved in the problem.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants are attempting to derive the magnetic field values based on given distances and questioning the interpretation of terms such as "from the axis" versus "from the coil plane." There is also a discussion about the components of the magnetic field and the angles involved in the calculations.

Discussion Status

The discussion is ongoing, with participants sharing their calculations and questioning the correctness of their interpretations. Some guidance has been provided regarding the components of the magnetic field, but there is no explicit consensus on the correct approach or definitions.

Contextual Notes

There appears to be some confusion regarding the terminology used in the problem, particularly concerning the reference points for measuring distances from the coil. This may affect the participants' calculations and understanding of the magnetic field's behavior.

Homework Statement
Circular current loop with radius of R = 0.3 cm and current I = 1.4 A

Calculate the magnetic field B within the distances of a) x1 = 0.17 cm and b) x2 = 2.3 cm from the axis.
Relevant Equations
B = (u0/2) * (IR^2) / (x^2 + R^2)^(3/2)
This should be pretty straightforward and my take gives B = 0.000193*T for a) and B = 0.00000063 T for b).

Or have I misunderstood something?

I’m not passing the grader with the above answer.
 
It seems the B equation is for its x-directed component. To derive B just need the angle. Solved.

"From the axis"? Should be "from the coil plane"? Or a diametric axis?
"The axis" is usually understood to be the coil's major axis.
