The straight sections of the wire are oriented parallel to the radii of the arcs. The wire carries 2 A of current in the direction shown. 1) What is the magnetic field at the center of the circular arcs? 2) A 0.5-kg, 2.0-C charge passes through the center of the circular arcs moving at 1.0 x 10 6 m/s [N20W]. Do NOT ignore gravity. What is its acceleration? A coaxial cable consists of a cylindrical wire of radius 15 cm and a cylindrical shell of inner radius 20 cm and outer radius 30 cm. The cylinder carries a current of 4.0 A toward the north, and the shell carries a 6.0 A current toward the The cylinder carries a current of 4....
