An infinitely long, thin wire has a known current of 2i, which flows in the negative x-direction. It is surrounded by an infinitely long, hollow cylindrical wire so the wires have a common axis. The hollow wire has inner radius A and outer radius B. A known current i, which is uniformly spread over the hollow wire, flows in the positive x-direction in the hollow cylindrical wire.

Consider an infinitely long straight wire with current I. Let's take the direction of the wire as the z-axis. Current is flowing in the positive z-direction. We already know the magnetic field. Find a vector potential for the case. Use the Coulomb gauge. 6. 7. For the example 1 of Chapter 6 in the textbook, obtain the magnetic field outside of the sphere. of a polarized object was the same as that of a bound volume charge pV. plus a...

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...
please kindly help me Three infinitely long, straight wires with distance d are placed in a row. The current flowing through each wire is I. Assuming that the radius of the wires is negligible (a) Find two spatial locations at which the magnetic field is zero. (b) Plot the magnetic field lines. (c) Supposing that the current in the middle wire changes to pposite direction, namely downwards, and then the middle wire moves an infinitesimal displacement (d), and other wires...
An infinitely long cylinderical capacitor initially has a linear charge density of + 5.60 nC/m (nanocoloumbs per meter) on the inner conducting cylinder and -5.60 nC/m on the outer conducting cylinder. The radius of the inner conducting cylinder is a = 0.060 m and the radius of the outer conducting shell is b = 0.160 m. See the figure of a small piece of the capacitor below: Part A Find the magnitude of the electric field 0.019 m from the...
stete the answer clearly please A very long, very thin straight line has a uniform charge per unit length of 2, where >. It is surrounded by a long, cylindrical, Insulating vinyl shell, which has an inner radius a and outer radius b. The line lies along the central axis of the cylindrical shell. The cylindrical shell has a uniform volume charge density p, where p > 0. (Both the line and the shell are long enough to approximate them...
Problem 2 (15 points): Consider the coaxial arrangement of two very long, thin hollow conductors shown in the figure. Assume that a constant current / flows in one direction on the inner conductor, and a constant current 31 (i.e. three times the current) flows in the opposite direction on the outer conductor. Can one use Ampere's Law to find the magnetic field at any point due to this configuration of currents, or should one use the Biot-Savart Law? Please explain....
