- Problem 1: Two long thin parallel wires are 0.1 m apart and each wire carries a current of 12 A. The current for the wire on the left is into the page and the current for the wire on the right is out of the page. What is B at point P, 0.08 m from one wire and 0.06 m from the other wire? Hint: Point P is on the corner of the right triangle with the right angle.

The inner cylinder has radius a = 2 cm and caries a total current of I1 = 1.0 A in the positive z-direction (pointing out of the page). The outer cylinder has an inner radius b = 4 cm, outer radius c = 6 cm and carries a current of I2 = 2.0 A in the negative z-direction (pointing into the page).

The cable consists of a solid inner conductor of radius r = 0.5 cm that is surrounded by a cylindrical tube of inner radius ry = 0.8 cm and outer radius r = 1.9 cm. The conductors carry equal and opposite currents / = 4 A but the current density varies linearly with the distance from the center for the inner conductor (j = cr) while it is distributed uniformly for the outer conductor.
