1. A coil arrangement comprising:
a first coil arrangement and
a second coil arrangement formed to be spaced apart at a predetermined interval and having a mirror image in a spaced apart direction, and
wherein the first coil arrangement comprises at least one first half period and at least one second half period formed adjacent to each other,
wherein the at least one first half period comprises at least two coils having anti-parallel current flowing directions,
wherein the at least one first half period and the at least one second half period have mirror image with respect to an interface between them wherein a direction of a magnetic field formed between the first half of the first coil arrangement and a first half of the second coil arrangement corresponding to the first half of the first coil arrangement is formed in a first direction facing each other,
wherein a direction of a magnetic field formed between the second half of the first coil arrangement and a second half of the second coil arrangement corresponding to the second half of the first coil arrangement is formed in a second direction facing each other, and
wherein the first direction and the second direction are opposite to each other.
