An infinitely long wire carries a current of 1- 160 A. Randomized Variables. I= 160 A G Select from the variables below to write your expression. Note that all variables may not be required. a, B, Ho, , 0, d, g, h, I, j, k, m, P, r, t Part (b) If r= 0.11 m, calculate the numerical value of B in tesla. Numeric A numeric value is expected and not an expression. B = 100 Part (a) Consider a circle with a radius r and centered on the wire. Determine the magnitude of the magnetic field B at points along the circle in terms of I and r. Expression : B = B
