THE JOURNEY OF DIAMONDS
By some researchers from the University of Bristol and
the Carnegie Institution have an idea:THE DIAMONDS
HAVE JOURNEY TO CENTER OF EARTH.
Actually, some people think that diamonds are a symbol
of deep love and now it becomes true.
Brasilian diamonds can flow to the undersea lava it
means the earth carbon cycle which is associated with
the recyling diamonds.The purpose of this recyle is to
reach deeper parts of the earth.
In the originates mantle contains less carbon-13 by
the super deep diamonds the less carbon-13 number
will decrease much by this way we can easily reach the
deeper parts of earth.
In the lava eruptions from the surface of oceans’ floor
showed a fingerprint which is diamond on the basalt
rock.
The researchers think that by the quality of reaching
deep of the earth the scientist send different chemicals
to find different ways to solve earth’s another problem.

WHY DO MAGNETS STICK?
Magnets stick together because they have a magnetic field
around them, and this field both pulls on and pushes away
other magnets. You’ve realized that when you played with
magnets like those that stick to your refrigerator, you know
that sometimes they stick to each other, but that they also
can push each other away, depending on which way the
magnets. Each magnet has a north pole and a south pole
and the north end of one magnet will stick to the south
end of another magnet. But if two north poles or two
south poles are placed near each other, the magnets will
push each other away. But, ıs this really the answer of why
magnets stick together? Definitely NO.
The explanation above
doesn’t inform you about
HOW magnets pull and
push on each other. To find
out the answer of sticking
in magnets, firstly we need
to think about what creates
a magnetic area. As we
mentioned the magnets
on your refrigerator, always have a magnetic field what is
called as permanent magnets. The secret of permanent
magnets is in the material they’re made of, which usually is
metal that contains a lot of iron.
All those materials are made up of atoms, which contains
electrons, protons and neutrons. And electrons are like some
small copies of magnets. In most materials the magnetic
clouds of electrons move in all different directions, so they
neutralize each other and there is no large magnetic field.
But in iron and a few other metals, these countless small
magnets moves in approximately the same direction. Each
magnetic area adds to and reinforces all the others. The
total effect creates a noticeable magnetic field, which will
pull and push on other, nearby magnets.
Also, we can create a magnetic
field with moving electric
charges. Electric charges that
are standing still exert same
electric forces on the objects
around them. But electric
charges that are moving exert
changing electric forces on the
objects around them. If the
changing electric forces are
all added up as the charges go by, the result is a magnetic
field. And all theese progresses explain the answer of the
question nearly.
