Reference no: EM13309454

A wire of radius a is surrounded by a cylindrical conductor of inner radius a and outer radius 2a. The two conductors are insulated from each other and carry current in opposite directions. The current density is the same in each conductor. Use ampere's law to find the radius at which the magnetic field is zero.
