  2. Eddy-current testing - Wikipedia

    en.wikipedia.org/wiki/Eddy-current_testing

    In the traditional version of eddy current testing an alternating (AC) magnetic field is used to induce eddy currents inside the material to be investigated. If the material contains a crack or flaw which make the spatial distribution of the electrical conductivity nonuniform, the path of the eddy currents is perturbed and the impedance of the ...

  3. Eddy current - Wikipedia

    en.wikipedia.org/wiki/Eddy_current

    In electromagnetism, an eddy current (also called Foucault's current) is a loop of electric current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction or by the relative motion of a conductor in a magnetic field. Eddy currents flow in closed loops within conductors, in planes ...

  4. Eddy (fluid dynamics) - Wikipedia

    en.wikipedia.org/wiki/Eddy_(fluid_dynamics)

    In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid is in a turbulent flow regime. [2] The moving fluid creates a space devoid of downstream-flowing fluid on the downstream side of the object.

  5. Remote field testing - Wikipedia

    en.wikipedia.org/wiki/Remote_field_testing

    Remote field testing (RFT) is a method of nondestructive testing using low-frequency AC. whose main application is finding defects in steel pipes and tubes. [1] RFT is also referred to as remote field eddy current testing ( RFEC or RFET ). [ 2 ]

  6. Electromagnetic testing - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_testing

    If the test is set up properly, a defect inside the test object creates a measurable response. The term "electromagnetic testing" is often intended to mean simply eddy-current testing (ECT). However, with an expanding number of electromagnetic and magnetic test methods, "electromagnetic testing" is more often used to mean the whole class of ...

  7. Skin effect - Wikipedia

    en.wikipedia.org/wiki/Skin_effect

    Cause of skin effect. A main current I flowing through a conductor induces a magnetic field H.If the current increases, as in this figure, the resulting increase in H induces separate, circulating eddy currents I W which partially cancel the current flow in the center and reinforce it near the skin.

  8. Nondestructive testing - Wikipedia

    en.wikipedia.org/wiki/Nondestructive_testing

    The six most frequently used NDT methods are eddy-current, magnetic-particle, liquid penetrant, radiographic, ultrasonic, and visual testing. [3] NDT is commonly used in forensic engineering , mechanical engineering , petroleum engineering , electrical engineering , civil engineering , systems engineering , aeronautical engineering , medicine ...

  9. Testing and inspection of diving cylinders - Wikipedia

    en.wikipedia.org/wiki/Testing_and_inspection_of...

    A hydrostatic test involves pressurising the cylinder to its test pressure (usually 5/3 or 3/2 of the working pressure) and measuring its volume before and after the test. A permanent increase in volume above the tolerated level means the cylinder fails the test and must be permanently removed from service. [3]: sect. 5.7.3
