In a standard practical transformer, the core is explicitly constructed out of soft iron primarily to

Professor PC Thomas Classes · Answer

(b) : Soft iron is chosen for transformer cores because it has very high magnetic permeability (which ensures nearly all magnetic flux is tightly linked between the primary and secondary coils) and a narrow hysteresis loop (which minimizes hysteresis energy losses during the continuous magnetization and demagnetization cycles of AC). Lamination is what minimizes eddy currents, not the material choice itself.
