Infinitely long filamentary conductors are located in the y = 0 plane at x = n meters where n = 0, ±1, ±2,... Each carries 1 A in the az direction.

(a) Find H on the y axis. As a help,

(b) Compare your result of part (a) to that obtained if the filaments are replaced by a current sheet in the y = 0 plane that carries surface current density K = 1az A/m.
