Answer» Answer: 3 Explanation: The soft iron core increases the strength of the MAGNETIC field inside a TRANSFORMER. The main purpose of USING an iron core in a transformer because iron is a magnetic material and it is EASILY available everywhere. The core is laminated to REDUCE the Eddy current and hence Eddy current losses |
