What is the magnetic field outside the cable

Reference no: EM13564619

A coaxial cable has a center conductor and an outercylindrical conductor with an insulating material in between. Current can flow through the center conductor to some device andthen return to the source through the outer conductor.

(a) What is the magnetic field outside the cable if a currentof 2 A is flowing to and from a device?

(b) How would the magnetic field be different if the twoconductors were parallel conductors as in a lamp cord?
