A)
Yes, current density is uniform
B)
Current, I = (5/4) Is = 1.25 x 5 = 6.25 mA
rs2 = 5.3 mm^2 = 5.33 x 10^-6 m^2
Slope = 0.00625/0.00000533 = 1172.61 A/m^2
Current density, J = 1172.61/pi = 373.25 A/m^2

Chapter 26, Problem 006 Your answer is partially correct. Try again. A certain cylindrical wire carries current. We draw a circle of radius r around its central axis in Figure (a) to determine the current i within the circle. Figure (b) shows current i as a function of r2. The vertical scale is set by is = 4.2 mA, and the horizontal scale is set by G2-4.6 mm2. (a) Is the current density uniform? (b) If so, what is its...

An infinitely long, straight, cylindrical wire of radius R carries a uniform current density J. Using symmetry and Ampere's law, find the magnitude and direction of the magnetic field at a point inside the wire. For the purposes of this problem, use a cylindrical coordinate system with the current in the +z-direction, as shown coming out of the screen in the top illustration. The radial r-coordinate of each point is the distance to the central axis of the wire, and...

A long cylindrical conductor of radius 54cm carries a current. The current density is not uniform over the cross section of the wire, instead is is given as J = 7r. How much current is enclosed in an Amperian loop of radius 29? Note: If we had a uniform current, then we could simply multiply a current density by an area (pi r2) to get the current. Since we are dealing with a non-uniform current, we must instead take an...
