Challenge Problems
Push your limits with challenges.
Question 1
Given a material with a known B-H curve, calculate the area of the hysteresis loop that represents energy loss in a cycle, if B increases linearly to a maximum before falling back.
💡 Hint: Visualize the shapes that compose the hysteresis loop.
Question 2
Analyze the performance of a transformer material with high coercivity and narrow hysteresis loop. Discuss its suitability for different applications.
💡 Hint: Directionally assess how these characteristics align with transformer design needs.
