12PRACTICE PROBLEM
Consider a long cylindrical electrode of radius R. The electrode has a current density given by J = J₀ (1 - r/R), where J₀ is a constant, R is the electrode radius, and r is the distance from the electrode center. What is the magnitude of the magnetic field inside the electrode at a radius r if current I is passing through it?
