The figure below shows a long conducting coaxial cable and gives its radii ). The inner cable has a uniform current density of , and the outer cable carries a uniform current 4.5A flowing in opposite direction. Assume that the currents in each wire is uniformly distributed over its cross section. Determine the magnitude of the magnetic field in terms of at a distance from the center of the cable. Express your answer using two decimal places.
Expert Answer
Ampere's circuital law will be used to evaluate the magnetic field at the given distance.Given:Radius of inner solid wire, Inner Radius of cable, Outer Radius of cable, Current Density of solid wire, Current flowing over the cable, Distance at which magnetic field is to be calculated, Objective: To calculate the magnetic field at Ampere's circuital law involves the current enclosed within the loop, so the current enclosed will be evaluated.
