A material suitablefor making core of a transformer should have (i) a narrow hysteresis curve so as to minimise energy dissipation during each magnetisation cycle and (ii) a high resistivity to lower eddy current losses.

Two characteristic properties of materials suitable for making the core of a transformer are:
High Magnetic Permeability: The material should have high magnetic permeability to efficiently conduct magnetic flux and reduce energy losses.
Low Hysteresis Loss: The material should exhibit low hysteresis loss, meaning minimal energy is wasted when the magnetic field alternates, ensuring efficient operation of the transformer.
