2. EMF measurement - Wikipedia

   en.wikipedia.org/wiki/EMF_measurement

   An EMF meter is a scientific instrument for measuring electromagnetic fields (abbreviated as EMF). Most meters measure the electromagnetic radiation flux density (DC fields) or the change in an electromagnetic field over time (AC fields), essentially the same as a radio antenna, but with quite different detection characteristics.

5. Electromagnetic field - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_field

   An electromagnetic field (also EM field) is a physical field, mathematical functions of position and time, representing the influences on and due to electric charges. [1] The field at any point in space and time can be regarded as a combination of an electric field and a magnetic field .

6. Eddy-current testing - Wikipedia

   en.wikipedia.org/wiki/Eddy-current_testing

   Eddy current testing (ECT) as a technique for testing finds its roots in electromagnetism. Eddy currents were first observed by François Arago in 1824, but French physicist Léon Foucault is credited with discovering them in 1855. ECT began largely as a result of the English scientist Michael Faraday's discovery of electromagnetic induction in ...

7. Electromagnetic testing - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_testing

   Electromagnetic testing (ET), as a form of nondestructive testing, is the process of inducing electric currents or magnetic fields or both inside a test object and observing the electromagnetic response. If the test is set up properly, a defect inside the test object creates a measurable response. The term "electromagnetic testing" is often ...
