A long, straight wire carries a current I0 and produces a magnetic field B0 at a distance r0 from the wire’s center. Part A: In terms of B0, determine the magnetic-field strength at a distance r0/2 from the wire’s center. Part B: In terms of B0, determine the magnetic-field strength at a distance 3r0 after the current is increased to 6I0.
