Uses of very large magnetic fields

[trini]

Ok, so i was browsing around wiki and read about something called a magnetar, which is a very dense neutron star producing magnetic fields in the order of 10 gigatesla. According to the write up, photons split up readily into 2 or more photons. now i know the most powerful magnets we have available for experimental purposes is about 1000 T, my question is, hypothetically of course, what would be the potential uses of a powerful reproducable field in the order of 100,000+Tesla to modern research?

Who cares about research?! We could float haha... look up Diamagnetic Levitation :)

To make humans fly about 50 Tesla should be enough.

You could safely crash land astronauts on e.g. Mars (like we sent the Mars rovers or the Pathfinder) using magnetic fields. When the spacecraft hits the surface, they will be accelerated at perhaps 30 g. But if this force is transferred to the volume of the body in a more or less uniform way (uniform per unit mass), then no stresses will build up in the body. It is similar to being in free fall while accelerating at 30 g in a gravitational field.

maybe we could make cosmic rays:

1000T sounds high..I though the LHC was around ten or so?
in any case, I bet CERN would love to be able to exchange their high energy and apparently fragile magnets for something more powerful and efficient...

splitting one photon into two photons seems spooky...

The strongest magnetic field that you are ever likely to encounter personally is about 10^4 Gauss if you have Magnetic Resonance Imaging (MRI) scan for medical diagnosis. Such fields pose no threat to your health, hardly affecting the atoms in your body. Fields in excess of 10^9 Gauss, however, would be instantly lethal. Such fields strongly distort atoms, compressing atomic electron clouds into cigar shapes, with the long axis aligned with the field, thus rendering the chemistry of life impossible. A magnetar within 1000 kilometers would thus kill you via pure static magnetism -- if it didn't already get you with X-rays, gamma rays, high energy particles, extreme gravity, bursts and flares...
In fields much stronger than 10^9 Gauss, atoms are compressed into thin needles. At 10^14 Gauss, atomic needles have widths of about 1% of their length, hundreds of times thinner than unmagnetized atoms. Such atoms can form polymer-like molecular chains or fibers. A carpet of such magnetized fibers probably exist at the surface of a magnetar, at least in places where the surface is cool enough to form atoms.
