Im sure some ATSer will correct me if I am wrong.
It appears as if that metal is being heated up via an induction current, and this explains the rolling/rotation.
An induction furnace heats things up through high amounts of electro-magnetic energy passing through the coil. When you have current passing around
something magnetic, it exerts a force on it, and you see an attempt to counteract this in the induction loop via the looped section in the copper
pipe. The force exerted follows the "right hand rule" ( en.wikipedia.org...
) along the path of the current through the
If it started out as a ball, it would probably begin to spin right away, and the reason the cylinder didn't is most likely due to it being a metal,
and thus exerted an electro-magnetic force as well augmenting and counter acting the right had rule preventing it from rolling right away.
Now for the fun part the metal that was dropped into the induction furnace took on the round shape it had, and eventually dropping. When magnetic
metals (even ones with very weak magnetic properties that don't exhibit them in normal conditions) are in a solid form they are made up of crystals
with similar polarity, the more magnetic the metal more likely these crystals will line up with one another and exhibit the properties of your every
day magnet. However as this metal is heated up in the induction loop, these crystals disassociate with one another due to the heat breaking down the
crystal structure, and lose their magnetic properties. You can see as it heats up it stars forming a rounder cylindrical shape as gravity is also
acting on it pulling some of it's mass downward, until the metal is completely melted. Once the metal is completely melted there is no longer
anything holding the crystals together, and the magnetic force applied to it from the induction loop can no longer hold it in place. Resulting in
that beautiful granite looking splatter at the end of the video.
Also I just cheated, and found out that the metal used here is aluminum, which normally isn't considered magnetic, but under instances of very strong
magnetic fields it does show characteristics of a magnetic metal.
and there are a lot of "stick" jokes in the comments section. I highly recommend using google translate for them.
