4. Jo(1- Consider a filled cylindrical wire with radius R and variable current density flowing through wire is given by J = Determine the magnetic field of such a current outside of this cylindrical wire. You can take the normal vector of the surface (where current flows) in the same direction with the current density (let's say in upward direction). No need to calculate B-field inside the solenoid. Hint: Consider using Ampere's law for closed loops.
