The Magnet Falling Through Ring model shows the dynamics and the induced current when a magnet falls through a conducting ring.

The current in the ring is computed by electromagnetic induction using to Faraday's law and the induced emf is proportional to the negative of the rate of change of magnetic flux ?. The direction of the induced current is determined by Lenz's law, the induced current produces magnetic field which tends to oppose the change in magnetic flux that induces such currents.

The Magnet Falling Through Ring model was created using the Easy Java Simulations (Ejs) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the ejs_mosem2_em_MagnetFallingThroughRing.jar file will run the program if Java is installed.

Please note that this resource requires at least version 1.5 of Java (JRE).

notice the electrons are space too near each other

perhaps a better visualization of the electrons (red balls) would be possible from the an increased in the spacing between them and a slow down of the angular velocity.
refer to http://phet.colorado.edu/en/simulation/faraday
they have done the student research on visualization of electrons in electromagnetic induction, could be useful to look at it.

currently, i cannot make out the motion of the electrons easily.

if time permits, i will help change it :)
