Core of the transformer is made up of
Correct answer: A. Soft iron
- A. Soft iron
- B. Steel
- C. Iron
- D. Alnico
Explanation
Transformer cores require a material that can be easilymagnetized and demagnetized with low energy loss. Softiron is used because it has high magnetic permeability andlow coercivity, minimizing hysteresis losses during the ACcycle.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
