CORE LOSS Meaning and
Definition
-
Core loss refers to the energy dissipated in a magnetic core due to the flow of alternating current (AC) through it. It is an important concept in electrical and electronic engineering, particularly in the study of transformers and inductor designs.
In an AC circuit, the magnetic core of a transformer or inductor is subjected to a changing magnetic field as the current alternates. This changing magnetic field induces voltage within the core material and causes energy losses due to hysteresis and eddy currents. These losses are collectively referred to as core loss.
Hysteresis loss occurs when the magnetic domain within the core material aligns and re-aligns with the changing magnetic field, resulting in energy dissipation. Eddy current loss refers to the energy lost due to the circulation of small, localized currents induced within the core material.
Core loss is typically represented in terms of power loss, usually given in watts. It is an undesirable effect in electrical devices as it causes inefficiencies, generates heat, and reduces the overall efficiency of the transformer or inductor. Minimizing core loss is a key aspect of designing efficient electrical systems.
Engineers consider core loss during the design process to select appropriate core materials and determine the optimal size and shape of the core. Various measures can be taken to mitigate core loss, such as using laminated core designs to reduce eddy currents or selecting materials with lower hysteresis characteristics. Efficient core design minimizes core loss, improves energy efficiency, and results in reliable and high-performance electrical devices.

Etymology of CORE LOSS
The term "core loss" comes from the combination of two separate words, "core" and "loss".
1. Core: In this context, "core" refers to the magnetic core of electrical transformers and inductors. The core is a crucial component that is typically constructed from magnetic materials, such as iron or various alloys. It provides a closed magnetic circuit, directing the flow of magnetic flux generated by an electric current passing through the coil. The use of a core helps to increase the efficiency and performance of electrical devices.
2. Loss: In the field of engineering, "loss" generally refers to the dissipation or decrease in usable energy during a process. It represents any energy that is converted into a form that is not useful for the intended purpose.
Combining these two terms, "core loss" specifically refers to the energy losses that occur in the magnetic core of electrical transformers and inductors.
