The discussion revolves around calculating the total force experienced by a rectangular loop in a magnetic field defined by B = (6x, -9y, 3z). The loop is situated in the z = 0 plane with specified dimensions and a current flowing counterclockwise.
Some participants express uncertainty about their approach and the necessity of intermediate steps to derive additional data. There is ongoing exploration of the implications of reversing the current on the resultant force, with no explicit consensus reached on the calculations.
Participants note the requirement to show previous work and question whether all necessary information has been provided for the problem.
1) according to our guidelines, you need to show us what you have doneBaracabacca said:Help!
Given that B = (6x, -9y, 3z) find the total force experienced by a rectangular loop in the z = 0 plane:
Loop defined as...
1<x<3
1<y<2
with 5 Amp current flowing COUNTERclockwise.
Baracabacca said:1) I guess I got a little anxious with the submit button!
I'm having problems setting up the equation.
2) I believe we're to use the equation: F = Int(dl x B) (where "x" indicated a cross product.)
I know I need to apply superposition to the loop - doing the integral for each of the four sides of the loop.
My problem comes from finding dl. Maybe I'm approaching the problem from the wrong angle. I initially thought you would use the integral relating B and the length of the loop in differential form.
3) I've submitted all information given, but I'm unclear if there's an intermediate step to solve extra needed data.
Baracabacca said:With that analysis I keep getting the total resultant force as zero. Does this make any sense?
