    Designing a simple magnetic field gen with a straight wire. Need current density

    Homework Statement Need to design a simple magnetic field generator of radius a= 2mm. The solid metal wire must carry a current density, jw, uniformly distributed over its cross section. The current density that must be found must have a magnetic field at a radial distance of r= 8mm from the...
