2. Eddy-current testing - Wikipedia

   en.wikipedia.org/wiki/Eddy-current_testing

   This is the basis of standard (pancake coil) ECT. NDT kits can be used in the eddy current testing process. [6] ECT has a very wide range of applications. Since ECT is electrical in nature, it is limited to conductive material. There are also physical limits to generating eddy currents and depth of penetration . [7]

3. 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 ...

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. Alternating current field measurement - Wikipedia

   en.wikipedia.org/wiki/Alternating_Current_Field...

   Alternating current field measurement (ACFM) is an electromagnetic technique for non-destructive testing detection and sizing of surface breaking discontinuities. It was derived from the methods used in eddy-current testing and works on all metals, ferrous or non-ferrous. Since it doesn't require direct electrical contact with the surface it ...

6. 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 ...

7. Rail inspection - Wikipedia

   en.wikipedia.org/wiki/Rail_inspection

   Modern-day inspection cars now use multiple NDT methods. Induction and ultrasound methods can be used in rail inspection cars and operate at testing speeds of more than 30 mph (48 km/h). Increased Camera systems for detection of broken joint bars or missing bolts. Eddy Current systems for the detection of near-surface defects.

   DETROIT (Reuters) -U.S. automakers Ford Motor and General Motors will donate $1 million each, along with vehicles, to U.S. President-elect Donald Trump's January inauguration, company ...

9. Eddy-current sensor - Wikipedia

   en.wikipedia.org/wiki/Eddy-current_sensor

   Eddy current sensors are displacement sensors that use the principle of eddy current formation to sense displacement. These sensors measure shaft displacement in rotating machinery and have been around for many years as they offer manufacturers high-linearity, high-speed measurements, and high resolution. [ 1 ]
