The coils of a transformer are:
Correct answer: A. Magnetically linked
- A. Magnetically linked
- B. Electrically linked
- C. Both A and B
- D. Isolated with each other
Explanation
The explanation is: The magnetic flux of the primary coil is linked with the secondary coil.When current flows through the primary coil, it creates a magnetic field in the core, and this magnetic field is what induces a voltage in the secondary coil. The magnetic linkage is crucial for the transfer of energy from one coil to the other.

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.
