In order to enhance magnetic flux, the primary and secondary coils of the transformer are wound on:
Correct answer: A. Soft iron core
- A. Soft iron core
- B. Iron core
- C. Hard iron core
- D. Steel core
Explanation
The correct option is A. In transformers, the core is made of soft iron due to its high magnetic permeability, which enhances magnetic flux linkage between the primary and secondary coils. This efficient linkage is crucial for the transformer's operation, as it allows the magnetic flux generated by the primary coil to be effectively transferred to the secondary coil. Other materials like generic iron, hard iron, or steel are not suitable as they either lack the necessary magnetic properties or introduce additional losses, thus reducing efficiency.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
