Its just very interesting to how this earth has evolved if you see the
past then you can just get an idea that so many dust particles combined
to form a planet named earth .but you can just think how earth become a
magnet . this just simple science if you think of a magnet of any shape
which attracts metal pieces then we can analyse that it will not
attract those metal pieces at only one place . the metal pieces will be
attracted surroundingly &this is the type of the force which is present
inside the earth &which is named as gravitation.

Umm, you are confused. First of all, gravity and magnetism are not the
same. Gravity is attraction at a distance. Magnets do not attract from a
distance. Moreover, the strength of the gravitational force of a body is
directly proportional to its mass. Not so with a magnet. The strength of
a magnetic field is inversely proportional to the cube of the distance of a
ferous object from the magnet. And finally, magnets attract primarily
ferous objects. There is no such elemental limit to what gravity can
attract.
