SUMMARY
The discussion centers on the relationship between work (Wm) and back electromotive force (emf) in the context of steady current. It is established that when the current is steady, the back emf is zero, resulting in Wm being zero as well. However, the presence of magnetic field (B) due to steady current indicates that there is still energy stored in the system. The inconsistency arises from the transition from zero current to steady current, which requires a changing current to store energy in Wm, yet once steady, no additional work is stored.
