SUMMARY

The discussion centers on Lenz's Law and its implications for electromagnetic induction. When a magnet is moved through a loop, a change in magnetic flux induces an electromotive force (emf) and a current to counteract the change in magnetic field. The conversation highlights the necessity of an electric field generated by the variable magnetic field to initiate particle movement, emphasizing that the magnetic force itself does not perform work. This understanding clarifies the relationship between magnetic fields and induced currents in electromagnetic systems.

So I was busy trying to imagine the ways in which lenz's Law would work physically. So I imagined a loop through which a magnet is brought and after that the magnet is pulled out of the loop a current is induced in order to keep up the magnetic field. So in this case the flux would go down which in turn would produce a positive emf and in its turn a current. Put as I was trying to imagine something struck me odd, why would particles start moving? A mere change of magnetic field is not enough to make a particle move because in order for a particle to move it has to has to have a force moving it and the magnetic force isn't the cause because it never does work so why does a current starts
