What is the magnitude of the current's magnetic field at the following radial dis, ?

  1. Nov 15, 2005 #1
    Figure 29-62 shows a cross section across a diameter of a long cylindrical conductor of radius a = 2.00 cm carrying uniform current 154 A. What is the magnitude of the current's magnetic field at the following radial distances?

    I figured out parts, A, C, and D. BUt can't get B to work:
    (b) 1.15 cm
    I tried
    PERM = 4PIE-7, I = 154;
    B = PERM*I;

    which was wrong,
    Tried:
    B = [PERM*I]/(2PI*R);
    Where R = .0115m, which was wrong;
    Any ideas what i'm doing wrong here>? :eek:
