Abstract
A magnetic-field-detecting and/or generating apparatus comprises a non-ferromagnetic tip with a longitudinal member of ferromagnetic material embedded in the tip. Further, magnetic-shield means is arranged around the tip. At the end of the longitudinal member a magnetic-field device is arranged. The same principle can be applied to read/write heads for use in magnetic-storage devices.
