The book elegantly argues that you cannot design a good magnetic component by mastering only one of these domains. A transformer with perfect electrical properties but poor thermal design will fail. A choke with excellent inductance but inadequate magnetic headroom will saturate. The "Trilogy" teaches the interplay between these three forces.
