Eddy-current testing (also commonly seen as eddy current testing and ECT) is one of many electromagnetic testing methods used in nondestructive testing (NDT) making use of …

Mar 7, 2026 · Eddy current testing uses electromagnetic induction to detect flaws in conductive materials without causing damage. Here’s how it works and where it’s used.

Eddy current testing is based on Faraday’s Law of Electromagnetic Induction. When an alternating current flows through a coil, it creates an oscillating magnetic field. When this field approaches a …

Sep 6, 2025 · Understand eddy current testing in NDT. Learn how it works, its applications, benefits, and why this method is vital for safety and quality assurance.

Eddy Current Testing (ECT) involves generating eddy currents within a material and observing the interaction between these currents and any present flaws or discontinuities. The fundamental …

Aug 12, 2025 · It works by inducing electrical currents (known as eddy currents) into the material, then monitoring how these currents are affected by any defects, changes in thickness, or material …

Eddy Current Testing (ECT) is a powerful NDT method used to detect surface and near-surface defects in conductive materials. By using electromagnetic induction, ECT identifies cracks, …

A specially designed coil energised with an alternating-current is placed in proximity to the test surface, generating a changing magnetic field that interacts with the test-part and produces eddy currents in …

When alternating current is applied to the conductor, such as copper wire, a magnetic field develops in and around the conductor. This magnetic field expands as the alternating current rises to maximum …

In this article, we cover what eddy current testing is, how it works, and common testing applications and methods. You can find more specific details on eddy current testing within our tutorial.
