Science

For transformers operating near saturation, which consequence results from exceeding the magnetic flux density limit?

A)Increased core hysteresis losses occur
B)Primary winding resistance sharply decreases
C)Reduced circulating current in core
D)Improved voltage regulation is observed

💡 Explanation

Increased core hysteresis losses occur because exceeding flux density pushes the core material into magnetic saturation, which means increased energy is used reversing magnetic domains via magnetic hysteresis; therefore losses increase, rather than voltage staying consistent.
