An electric current is flowing through a long cylindrical conductor with radius a = 0.15 m. The current density J = 2.5 A/m2 is uniform in the cylinder. In this problem, we consider an imaginary cylinder with radius r around the axis AB.
Part (e) When r is greater than a, express the current inside the imaginary cylinder in terms of r, a, and J.
Part (f) Express the magnitude of the magnetic field, B, at r > a in terms of I and r.
Part (g) Express B in terms of J, a and r.
Part (h) For r = 2 a, calculate the numerical value of B in Tesla.
I already did the first few parts. I am most confused on parts e and g, how to derive the equations. Thanks so much!
The figure shows a cylindrical conductor with inner
radius a = 2.2 cm and outer radius b= 3.7 cm. The
current flowing in the cylinder is perpendicular to the
figure and directed outward. The magnitude of the
current density is given by J = cr² where c = 2.9 x
106 A/m² (r in meters). What is the magnitude of the
magnetic field at point P (at a radial distance from the
center midway between a and b (i.e., at r = (a+b)/2)?
Give your answer in μT.
