<p>A method and apparatus for measuring physical quantities using amorphous ferro-magnetic sensor elements 1, 1'. Reliance is placed on the change in switching field which causes such materials to exhibit the Barkhausen effect seen as the material is subjected to stress. In a preferred form of sensor two sensor elements 1, 1' of the same material are used, which have been pre-stressed to different degrees.</p> |
