Calculate magnetic field intensity

AI Thread Summary
The discussion revolves around calculating the magnetic field intensity (H) at two points due to two infinitely long parallel filaments. The calculations involve using Ampere's law and considering the correct distances and directions of the currents. Participants emphasize the importance of correctly determining the distances (Ry and Rz) and the direction of the magnetic field vectors at the origin and the second point (-1,2,2). The conversation highlights the significance of understanding the right-hand rule for determining the direction of the magnetic field. Ultimately, the participants work towards confirming the correct approach to solve the problem while clarifying misunderstandings about the geometry involved.

If the distance from either wire is fixed then no

OK, so how can we make life easier by altering the second observation point (-1,2,2) without changing H at any given (x,y,z)?

Ok so what you are saying is that it does matter

im really sorry man for dragging this out I am just trying to understand. That being said if you change positions of course you will change the strength, right?

As x changes, does H change?

I think so when I said no you said I was wrong?

Why would H change as you move along it, keeping the same perpendicular distance from it? The wire is infinitely long!

ok so i was correct before and it doesn't change

Yes. I didn't feel youunderstood why. Just gussing right does not help you understand.

Anyway, OK, so how do we write (-1,2,2) if we want to put the observation point in the yz plane? This step is not really necessary but helps to visualize things.

well your right I am not understanding. Do you have any tips on that? As to your question you should draw the x-axis line so that it is parallel to the two wires. One side of that line will lie in the yz plane which is where it should be marked

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?
 
  • #62
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.
