Calculate magnetic field intensity

Click For Summary

Discussion Overview

The discussion revolves around calculating the magnetic field intensity (H) generated by two infinitely long parallel filaments. Participants explore the application of Ampere's law and the geometric considerations necessary for determining H at specific points in space, particularly at the origin and at the coordinates (-1,2,2).

Discussion Character

  • Homework-related
  • Technical explanation
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant attempts to apply Ampere's law to find H at the origin and at (-1,2,2), using the equation H=H1+H2.
  • Another participant points out the need to consider the signs of the enclosed currents, which flow in opposite directions.
  • There is confusion regarding the correct computation of distances Ry and Rz, with multiple participants providing differing interpretations and corrections.
  • Participants discuss the direction of the magnetic field and the application of the right-hand rule (RHR) to determine the orientation of H at the origin.
  • One participant proposes that the H field should point in the same direction as the B field, leading to further discussion about the correct application of the RHR.
  • There is a suggestion to express the final answer in terms of unit vectors, and a participant questions whether to include units or present the answer in phasor form.
  • Another participant raises the question of whether the x-component of the observation point affects the calculation of H, leading to further exploration of the geometry involved.

Areas of Agreement / Disagreement

Participants express differing views on the correct computation of distances and the application of the right-hand rule. There is no consensus on the final answers for both parts of the problem, and the discussion remains unresolved regarding the implications of the x-component of the observation point.

Contextual Notes

Participants have noted limitations in their understanding of the geometry involved in calculating distances and the direction of the magnetic field. There are unresolved questions about the impact of the x-component on the magnetic field calculations.

Whoa I flubbed that up that wasnt what you asked at all heh. Well would it (0,2,2) so that the x part is eliminated?

Ok you will be happy I think i found a solution online that is right, I appreciate all the help on the problem. I am a little iffy on whether the solution is correct but I am just growing tired of this problem, and will come back to it later on.

Is it against the rules to ask if you can assist me with other issues I don't want an infraction?Sorry hope I am not being pushy or anything just wondering.
