Hello cyber citizens welcome to what the science
The most powerful magnet in the universe doesn't
look like a normal magnet instead it looks
like a planet
About five thousand light years away from
us lies the Stellar Monster called as magnetar
Awesome Intro
magnetar is a type of neutron star, which
is created when a star collapses under its
own Gravity when it runs out of hydrogen atoms
to continue its fission reaction
what make magnetar different from a normal
neutron star is that it has a magnetic field
as strong as 10 raised to 14 to 10 raised
to 15 gauss
A gauss is a unit of measuring magnetic flux
for comparison our earth magnetic field on
the surface is 0.6 gauss
a common commercial magnet is of 100 gauss
sunspots the most magnetic part of the sun
has 3000 gauss
the most powerful MRI machine ever created
has 70000 gauss
the strongest steady magnetic field that we
were able to produce in our labs is up to
4,50,000 gauss
A normal neutron star has one trillion Gauss
that is 10 raise to 12
so a magnetar is 100 to 1000 x more powerful
than a neutron star
a magnetar is so powerful that its magnetic
field can squeeze the atoms to form a long
and needle-shaped structure
even from thousands of km away a magnetar
can rip apart all the molecular bonds of your
body.
magnetar are so massive and dense that they
can curve the path of light itself
also the neutron star doesn't let all the
vibrations of light to pass through it acting
as a giant polaroid
so what makes magnetar different
stars rotate so does it's core
this rotation creates the magnetic field as
a result of a Dynamo effect
but when it collapses, a star losses much
of its mass and its radius decreases
this decrease in radius is accompanied with
increase in angular velocity because angular
momentum needs to be conserved
so with the right rotation rate temperature
and magnetic field, this dynamo mechanism
can increase the neutron star's magnetic field
to magnetar level
Magnetar can also produce the most intense
blasts in the universe
The crust of magnetar is twisted and turned
by immense magnetic field at the core
this friction can lead to starquake which
is a violent outburst of energy in the form
of Gamma radiation
we know this because, on 27th December 2004,
we witnessed one such Spectacular blast from
the Magnetar SGR1806-20, which partially ionized
Earth's upper atmosphere and damaged some
satellites
the energy output from this magnetar was so
enormous that within one fifth of a second
it released as much as energy as our sun would
in 2,50,000 years combined
but magnetars don't say that long, after 10000
years or so they settle down to a long-term
normal neutron star life, but still they are
dangerous and not to be fiddled with
but surely we can throw our words at it, so
feel free to type in your comments and let's
have a discussion about universe's own super
magnet
