ABSTRACT:
The magnetometer according to the invention comprises a logic unit (50) receiving a resonance detection signal, a digital processor (60) supplying a number N, a digital-analog converter converting said number into current for establishing a feedback. The measurement of the field is directly digitally given by the processor.
Use in magnetometry.
