Solution(By Examveda Team)

A ferrite core has less eddy current loss than an iron core because ferrites have high resistance. Eddy currents are circulating currents that are induced in a conducting material (like a core) when it is exposed to a changing magnetic field. These currents lead to energy loss in the form of heat due to the electrical resistance of the material.

Ferrite cores are made from materials that have high electrical resistance, which means they offer more opposition to the flow of eddy currents. As a result, the eddy current losses in ferrite cores are significantly lower compared to materials with lower resistance, like iron cores. This property makes ferrite cores suitable for applications in high-frequency transformers and other electronic devices where minimizing energy losses is important.
