Download Solution PDFCONCEPT:
- Eddy Current: When a changing magnetic flux is applied to a bulk piece of conducting material then circulating currents is called eddy currents are induced in the material.
- Because the resistance of the bulk conductor is usually low, eddy currents often have large magnitudes and heat the conductor.
- Due to heating of the conductor there is a loss in energy. This loss is called eddy current loss.
EXPLANATION:
- The eddy current loss can be reduced by increasing the resistance of the core. So option 1 is not correct.
- The eddy current loss can be reduced by using a laminated core like in the above diagram. So option 2 is correct.
