What is the role of a transformer’s core?

• A. To store energy for later use
• B. To channel the magnetic field and reduce energy loss
• C. To provide physical support for wiring
• D. To convert electrical energy to mechanical energy

Answer: (B)

The role of a transformer's core is essential in its operation, particularly in how it affects the efficiency and functionality of the transformer. The core is primarily made from materials that are magnetically conductive, which is crucial because it channels the magnetic field produced by the alternating current in the primary winding. By channeling the magnetic field, the core enhances the magnetic coupling between the input and output windings, allowing for efficient energy transfer from one circuit to another while minimizing energy loss. This reduction of loss is vital because it directly impacts the transformer's efficiency; a well-designed core will reduce stray magnetic fields that could otherwise cause heating and energy waste. Moreover, the design of the core, including its shape and the type of materials used, plays a role in reducing hysteresis and eddy current losses, further improving performance. Overall, the core's role is crucial for maximizing the transformer's ability to operate effectively and efficiently in transmitting electrical energy.
