The current density in a cylindrical conductor of radius R = 50.9cm, varies as J(r) = Jo*r/R (in the region from zero to R), whereJo = 0.585 C/m2.
Find the magnitude of the magnetic field at r = 25.45 cm and at r =101.8 cm.
answer in teslas.
i know it has something to do with the integral of the function (iguess over the region 0 to R) but what does that mean. What is thefunction anyway? Also the integral should give the current"enclosed" how do i get that. perm. of free space * currentenclosed = answer right? THANKS SSOOOOO MUCH!!!
