Question: In a cylindrical coordinate system, a 2-m-long straight wire carrying a current of 5 A in the positive z-direction is located at r = 4

In a cylindrical coordinate system, a 2-m-long straight wire carrying a current of 5 A in the positive z-direction is located at r = 4 cm,  2, and, 1 m (a) If B = r0.2cos (T), what is the magnetic force acting on the wire?

1 m SA 4 cm -1 m- Figure P5.5: Problem 5.5.

(b) How much work is required to rotate the wire once about the z-axis in the negative -direction (while maintaining r = 4 cm)?
(c) At what angle is the force a maximum?

1 m SA 4 cm -1 m- Figure P5.5: Problem 5.5.
