Okay, that makes sense. Then the question becomes, on the very first time
the experiment is tried, what is the source of energy since the cube has not
been pulled away from the magnet.

From the Big Bang, where everything was separated
in the first place.

What "Big Bang"?
What evidence do you have for a "Big Bang"?



Also of interest is the fact that if you let the cube loose in the air so
that friction of sliding on the board is not in play, it will take just as
much human energy to pull the cube off the magnet as when the cube was
allowed to slide across the board which produced heat. What is the source
of energy that produced the heat?

When the cube hits the magnet, the kinetic energy of its
motion is dissipated as heat, vibration, and/or sound
(CLICK!).

When the cube slides with friction, some kinetic energy
is dissipated as heat along the way and the cube does not
accelerate as quickly or achieve as high a velocity before
impacting the magnet (smaller CLICK!).
