WebTiny eddy currents still exist, but they are much reduced because they exist only within each thin sheet. Uses of eddy current: Using eddy currents to see if a material or surface has any discontinuities, fractures, or faults without harming the material is one of the most common electromagnetic NDT methods. Electromagnetic damping is produced ... Web8 de nov. de 2024 · Let us now calculate the resistance offered by the lamination to the eddy current. Rlamination= Resistance offered by each lamination = 4k/A. Therefore, Eddy Current Loss in each Lamination = (emf induced)2 / Rlamination. = A (E/4)2 / 4k. = AE2/64k. As there are 4 laminations, hence total eddy current loss.

WebAnswer is C. Eddy current losses due to joule heating in the core that are proportional to the square of the transformer's applied voltage. Eddy current losses can be reduced by making the core of a stack of plates electrically insulated from each other, rather than a solid block; all transformers operating at low frequencies use laminated or similar cores.
