• A. reduce eddy current ✓
• B. reduce magnetic flux
• C. increase the magnetic flux
• D. reduce its efficiency

The reason for laminating the soft iron core of a transformer is to reduce eddy currents. Laminating the core involves insulating thin sheets of soft iron with a non-conductive material, such as varnish or oxide layers. This process helps to minimize the formation of eddy currents, which are induced currents that circulate within the core material and can lead to energy losses in the form of heat. By reducing eddy currents, laminating the core improves the efficiency of the transformer by minimizing energy wastage.
