Eddy Current

Eddy current (EC)-based methods measure a material''s response to electromagnetic fields over a specific frequency range, typically a few kHz to several MHz (Shull 2002). The principle is illustrated in Fig. 17.3. A magnetic coil with an AC induces a time-varying magnetic field, which causes an electric current to be generated in the test object.

What are Eddy Currents? – Definition, Causes, Applications

2021-12-2 · Eddy Current. Eddy currents flow through conductors like whirling eddies in a stream, and they are frequently formed in reaction to a changing magnetic field. They flow in closed loops perpendicular to the plane of the magnetic field plane, caused by changing magnetic fields. These are also known as Foucault''s Currents.

Eddy Current Dynamometers Archives

Multi-eddy configurations offer capacities to 10,000 HP or 100,000 foot-pounds of torque – and long-duration absorption (for lesser engines). Only axle-hub (or engine) dynamometers isolate HP from the inconsistencies of tire-to-roll traction – providing repeatable data that serious tuners and engineers need to compare against baseline tests.

Eddy Current

Eddy Current Principle. An eddy current is also called the Foucault current. Eddy currents are swirls of electric currents induced within conductors by a changing magnetic field within the conductor (self-inductance). Eddy current works on the principle of Faraday''s law of induction. The Eddy Current Principle works as the Self-inductance.
