1. A magnetic field sensing component comprising:
a serpentine structure of line elements, the serpentine structure comprising:
an array of line elements; each line element from the array of line elements being a magnetic field sensing structure; each line element having a first end and a second end; each first end being adjacent to another first end; each second end being adjacent to another second end; said array of line elements being part of the serpentine structure;first connecting elements, each first connecting element positioned to connect first ends of two adjacent line elements from the array of line elements; said first connecting elements being part of the serpentine structure;second connecting elements, each second connecting element positioned to connect second ends of the two adjacent line elements; said second connecting elements being part of the serpentine structure; andan array of flux concentrating structures; each one flux concentrating structure being disposed between two line elements from the array of line elements in the serpentine structure; wherein said each one flux concentrating structure is not disposed either over or under the serpentine structure; and wherein said each one flux concentrating structure is not disposed either over or under the first or second connecting elements.
