Detailed Solution

Concept: The eddy current loss is minimised by making the core with thin laminations.
The following are the energy losses in a transformer:
1. Eddy current loss: In the core, eddy current is produced by shifting magnetic flux. As a result, energy is wasted as heat. This can be mitigated by using a laminated core constructed of steel alloy.
2. Copper loss: the current route of the primary and secondary windings contributes to Joule heating. In addition, a certain quantity of energy is wasted as heat. To prevent this loss, thick cables with extremely low resistance are used.
3. Flux loss: Due to leakage, the primary loop's flux isn't completely connected to the secondary coil. Using a shell type core can help to limit this.
4. Hysteresis loss: This is because of the rehashed magnetization and demagnetization of the iron core brought about by the substituting input current. This can be limited by utilising alloys like metal or silicon steel.
They will happen when the conductor is exposed to a changing magnetic field. Because these currents are not responsible for accomplishing meaningful work, they cause an Eddy Current Loss (I2R loss) in the magnetic material. Eddy current loss is reduced by using thin laminations in the core.
Hence, the answer is laminations.
