Demagnetizer
| Глоссарий по архивному хранению медийных материалов |
Also known as a `degausser`, an electromagnet with a probe tip that can eliminate residual magnetism by touching it to elements of the tape path (such as tape heads and tape guides).

Desmagnetizador, испанский
Размагничивающее устройство, русский
Составная часть магнитопорошкового дефектоскопа или отдельное устройство, предназначенное для уменьшения значения намагниченности, оставшейся в материале объекта контроля после устранения внешнего намагничивающего магнитного поля, до допустимого уровня.

Electromagnet, английский
- Электромагнит
- A soft iron core surrounded by a coil of wire. the iron core becomes magnetic when an electric current flows through the wire.
- Ferromagnetic core surrounded by a coil of wire that temporarily becomes a magnet when an electric current flows through the wire. electromagnetic acoustic transducer (emat): transmitting transducer based on the force exerted on a current flowing in a magnetic field. a receiving transducer that detects the current produced by moving a conductor in a magnetic field. glossary 19.9 electromagnetic testing (et): nondestructive test method for materials, including magnetic materials, that uses electromagnetic currents, either alternating or direct current, to yield information about the test object. in nondestructive testing, the term electromagnetic testing is not applied to methods such as radiologic and thermographic testing, in which the interrogating energy is a form of electromagnetic radiation. electronvolt (ev): kinetic energy acquired by an electron in passing through a potential difference of 1 v in vacuum; 1 ev = ~1.60 j. the electronvolt is commonly used to express the energy of x-rays. emat: see electromagnetic acoustic transducer.
