ABSTRACT:
A previously charged capacitor is discharged through a coil having a core situated in the vicinity of the steel tooth. The discharge creates a surge of magnetic circulation whose attractive forces cause a bending of the steel tooth which then executes flexural vibrations. A sensor senses the flexural vibrations and furnishes an electrical signal whose amplitude and/or frequency characteristics are examined to detect defects in the tooth.
