Unformatted text preview: 5. Find the current density J r in free space that induces the magnetic field with m Wb a A z / 10 2 r r = 6. A conducting triangular loop carrying a current of I t is located close to an infinitely long, straight conductor with a current of I s as shown below. Calculate (a) the force on side 1 of the triangular loop, and (b) the total force on the loop. 7. An infinitely long tube of inner radius of a and outer radius of b is made of a conducting magnetic material. The tube carries a total uniform current I and is placed along the z-axis. If it is exposed to a constant magnetic field B o a , determine the force per unit length acting on the tube. 5A z 2m 4m 2m 2A...
