A long, straight wire with a circular cross section of radius R carries a current I. Assume that the current density is not constant across the cross section of the wire, but rather varies as J = αr, where α is a constant. Part A By the requirement that J integrated over the cross section of the wire gives the total current I, calculate the constant α in terms of I and R. Express your answer in terms of the variables I and R. Part B Use Ampere's law to calculate the magnetic field B(r) for r ≤ R. Express your answers in terms of I. Express your answer in terms of the variables I, R, r, and magnetic constant μ0. Submit Request Answer Part C Use Ampere's law to calculate the magnetic field B(r) for r ≥ R. Express your answers in terms of I. Express your answer in terms of the variables I, r, and magnetic constant μ0.A long, straight wire with a circular cross section of radius R carries a current I.
