Circular magnetization, английский
- Magnetization in an object resulting from current passed longitudinally through the object itself or through an inserted central conductor.
- Намагничивание объекта возникает в результате прохождения тока продольно через сам объект или через вставленный центральный проводник.
- Result of current flow technique or internal conductor technique where a circular magnetic field is imparted. see also field flow technique; right hand rule. compare longitudinal magnetization.
- Result of current flow or internal conductor techniques where flux lines are oriented along the circumference of the test object.

Transducer element, английский
- In an ultrasonic transducer, the piezoelectric crystal to be coupled to the test surface. also called the crystal. transducer, flat response: transducer whose frequency response has no resonance or characteristic response within its specified frequency band. the ratio between the upper and lower limits of the frequency band are typically not less than 500 khz. transducer, resonant: transducer that uses the mechanical amplification due to a resonant frequency (or several close resonant frequencies) to give high sensitivity in a narrow band, typically ±10 percent of the principal resonant frequency at the –3 db points. transducer, wide band: transducer whose response to surface displacements is relatively flat over a broad frequency range.
