Abstract
Products are disclosed for measuring electromagnetic fields. One embodiment has at least two coplanar magneto-resestive sensors. Each magneto-resistive sensor has a sensitive axis in the plane of the at least two coplanar magneto-resistive sensors. The at least two magneto-resistive sensors may be orthogonally arranged about a central point to measure orthogonal components of electromagnetic fields.
