A very long, hollow cylinder (radius 2.5cm) is formed by rolling up a thin sheet of copper. Electric charges flow along the copper sheet parallel to the axis of the cylinder. The arrangement is, in effect, a hollow tube of current 2.5A. Use Ampère’s law to find the magnetic field (a) outside the cylinder at a distance 6.1cm from the axis and (b) inside the cylinder at a distance 2.1cm from the axis. (Hint: For closed paths, use circles perpendicular to and centered on the axis of the cylinder.)

A long, hollow cylinder with inner radius R1 and outer radius R2 carries current along its length. The current is uniformly distributed over the cross-sectional area of the cylinder and has current density J. 1. Find the magnetic-field magnitude B as a function of the distance r from the conductor axis for points inside the hollow interior (r<R1). Express your answer in terms of the variables R1, R2, J, and r. 2. Find the magnetic-field magnitude B as a function...

A coaxial cable is formed by a long, straight wire and a hollow conducting cylinder with axes that coincide. The wire has charge per unit length λ = 7λ0, and the hollow cylinder has net charge per unit length λ = 6λ0. Use Gauss's law to answer these questions: What are the charges per unit length on the following surfaces of the hollow cylinder? (a) the inner surface (Use the following as necessary: λ0.) λinner = (b) the outer...

Constants Part A You are given a hollow copper cylinder with inner radius a and outer radius 3a. The cylinder's length is 200a and its electrical resistance to current flowing down its length is R. To test its suitability for use in a circuit, you connect the ends of the cylinder to a voltage source, causing a current I to flow down the length of the cylinder. The current is spread uniformly over the cylinder's cross section You are interested...

(1) Consider a very long uniformly charged cylinder with volume charge density p and radius R (we can consider the cylinder as infinitely long). Use Gauss's law to find the electric field produced inside and outside the cylinder. Check that the electric field that you calculate inside and outside the cylinder takes the same value at a distance R from the symmetry axis of the cylinder (on the surface of the cylinder) .
