True, the idea in mind is to accelerate a conductor in a magnetic field, at very high velocities, and would want to reduced the eddy current's magnetic breaking effect, best option i guess is just breaking the conductor up into the smallest pieces possible to reduce it so that it could be negligible. – Pupil.

Web25 de ago. de 2024 · Losses in a Transformer: There are two types of losses in a transformer: Core loss; Copper loss . Core loss: Core loss, which is also referred as iron loss, consists of hysteresis loss and eddy current loss. Hysteresis loss: Hysteresis losses can be reduced by using material that has less area of the hysteresis loop. WebEddy Current loss can be reduced by increasing the number of laminations. The laminations provide small gaps between the plates. As it is easier for magnetic flux to flow through iron than air or oil, stray flux that can cause core losses is minimized.
