Document Summary
Lecture 8 notes 3 - conservation of energy. Last note we looked at the appearance of the conservation of energy in the context of. We discovered why systems of induced currents dissipate energy. This being due to the fact that the energy is actually transferred to the system by the energy that changes the field (moves it closer) or area. This time we will look further into this and verify it (but honestly if you understand the concept at the bottom of the last note, there"s no point reading this. Imagine we are moving a wire with a velocity v from the area of being under the influence of the magnetic field to the 0 area. Thus this change in flux is = to an emf that is created. Since energy is dissipated when the current flows, we must have to do work to pull the wire (and create the velocity).
