Amorphous steel is utilized to further ______ within the core.

• A. Reduce the losses
• B. Increase the saturation
• C. Improve mechanical strength
• D. Raise the temperature

Answer: (A)

Reducing losses in the magnetic core is what this material choice aims for. Amorphous steel has a disordered atomic structure that lowers energy needed to realign magnetic domains, cutting hysteresis losses. It also has higher electrical resistivity than crystalline steels, which suppresses eddy currents. Together, these factors substantially reduce core losses during operation, improving efficiency and keeping the core cooler.

Increasing saturation is not the primary benefit here, and improving mechanical strength or raising temperature aren’t the main goals for transformer cores, so they don’t fit the intended use.
