... Ferromagnets have a much higher magnetization than paramagnets. In addition, the phenomenon of ferromagnetism comes about due to a totally dierent mechanism. In ferromagnetic materials, the elementary magnets act in a cooperative fashion, forcing neighbouring magnets to align within themselves. Soo ...

The Ideal Transformer
... Thus, we find that for a step-up transformer, the primary resistance is much greater than that of the load resistance on the secondary. Conversely, a step-down transformer will exhibit a primary resistance R1 that is much smaller than that of the load. One more important note! We applied conservatio ...
