An electric current is flowing through a long cylindrical conductor with radius a = 0.75 m. The current density J = 9.5 A/m2 is uniform in the cylinder. In this problem we consider an imaginary cylinder with radius r around the axis AB.
1. For r = 0.5 a, calculate the numerical value of B in Tesla.
2. Express the magnitude of the magnetic field, B, at r > a in terms of I and r.
3. Express B in terms of J, a and r.
4. For r = 2 a, calculate the numerical value of B in Tesla.
A particle of charge q moves in a circle of radius r with speed v. Treating the circular path as a current loop with an average current, find the maximum torque exerted on the loop by a uniform field of magnitude B.
In a particular region there is a uniform current density of 15 A/m2 in the positive z direction. What is the value of when that line integral is calculated along a closed path consisting of the three straight-line segments from (x, y, z) coordinates (4d, 0, 0) to (4d, 3d, 0) to (0, 0, 0) to (4d, 0, 0), where d = 20 cm?
