for the PHYS 312 HW regarding the magnetic field of the varying - TopicsExpress



          

for the PHYS 312 HW regarding the magnetic field of the varying current density wire, did anyone else get that it is constant? I have looked through several resources for help on this and when I do the math, all I end up with is an R^3 term in the denominator and nothing in the numerator. when I apply amperes law and substitute in the varying current using J, the rs cancel on both sides. I cant figure out what I have done wrong :(
