Abstract
Abstract A magnetic sensor characterised by a sheetlike support (254), and a plurality of magnetically sensitive elements (250) each having a preselected sensitive direction disposed on said support (254), said sheetlike support (254) being folded so that said magnetically sensitive elements (250) are non-coplanar with one another. A method of making the sensor comprises the steps of securing a plurality of magnetically sensitive elements (252) each having a sensitive direction to a generally planar, sheetlike support (254), and then folding said support (254) so that portions of said support (254) bearing different magnetically sensitive elements (252) lie in different planes.
