Simulation of a magnet moving at constant velocity through a solenoid

While looking at the simulation, follow the graph plotted as the magnet moves through the solenoid. Lenz's law agrees with the conservation of energy by resisting the change that causes it.

Mechanical energy changes to electrical energy and in turn thermal energy due to the resistance of the wires.

Current flows from low to high potential in this case. Remember it is EMF (electromotive force) we are looking at here so in the same way IN a cell/battery current flows from low to high potential.

What if the magnet is not at constant velocity but falls from rest through the solenoid?

Think about it before watching the video below.
