Homework Statement
find the magnetic field at point P in the figure below: (see attachment)
Homework Equations
magnetic filed B = integral[dB] = mu_0/4pi (integral[I(dL)/r^2]) where mu_0 is constant = 4pi*10^-7, I is current, dL is change in length, r is radius
The Attempt at a Solution
based on looking at the diagram, i assume i as the current, to be constant, and how do i factor in the L, specifically the change in L, dL from the diagram, which length am i supposed to use/measure, is it just L/2? or is the radius r = L/2?
