Why is it important that the core of a transformer pass through both coils?
To Explain:The importance of the core to pass through both coils in a transformer.
Answer to Problem 37A
To increase the number of magnetic field lines produced in primary coils and intercepted by the secondary coil.
Explanation of Solution
Introduction:
As the core passes through the coils, more magnetic field lines are produced.
The core of the transformer is made of soft iron. This core must pass through both coils (primary and secondary).As the core passes through the primary coils, magnetic field lineswill be developed and when the core passes through the secondary coils, the magnetic field lines are intercepted. So, as the core passes through both coils, the magnetic field develops and more energy is stored in the coils.
Conclusion:
The core must pass through both the coils in a transformer so that the maximum number of magnetic field lines are generated in the primary coil and intercepted by the secondary coil.
