摘要
The device comprises a soft magnetic alloy magnetic circuit (4) and, on this magnetic circuit, at least one winding (6, 8); the electrical voltage appearing across the terminals of the winding when the device is placed in a magnetic field (B1) leads to the saturation of the soft magnetic alloy of the magnetic circuit, enabling this magnetic field and its variations to be detected. The magnetic field may be maintained at a reference value on the basis of the detected field. Application to the regulation of the magnetic field in a free electron laser wiggler. IMAGE
