Why is the core of a transformer laminated?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Transformer Core**: The core of a transformer is a crucial component that helps in the efficient transfer of electrical energy between its primary and secondary coils through electromagnetic induction.

2. **Material of the Core**: The core is typically made of iron, which is a good conductor of magnetic fields. However, instead of using solid iron, transformers are constructed using laminated iron.

3. **Reason for Lamination**: The primary reason for using laminated iron is to reduce the formation of eddy currents. Eddy currents are loops of electrical current that are induced within conductors when they are exposed to changing magnetic fields.
