Give the magnitude of the magnetic field B(r) for r less than or equal to R where a long straight wire with a circular cross-section of radius R carrying current I, whose density is not constant across but varies as J = ar where a is a constant. b. a. B = μια r^3/8R B = Mar^2/3 c. B = μoa R^2/3 d. Boa R^3/3r
