Abstract
A flat coil assembly (10) comprising at least one electrically conductive layer (12) arranged in a substantially uniplanar spiral arrangement of loops with a void in a center of the spiral, and a core (14) made from mu-metal, wherein the core extending on one side of the uniplanar spiral arrangement over at least a first portion of the loops from an external loop to an internal loop, crossing over, through the void in the center and extending over at least a second portion of the loops on the other side of the uniplanar spiral arrangement.
