I am attempting to create a presentation on neutron stars. In this 
presentation, I will attempt to describe what an observer in a space craft 
feels and sees in steps as they approch the neutron star.  I believe the 
magnetic effects will be the most intersting.  There will be a region 
around the neutron star (depending on the magnetic strength of the star) 
where magnetism appears to act like gravity, but with strange differences.
For example, some substances will be repelled, some will be attracted.  I 
believe the human body will be repelled because it is diamagnetic 
(contains mostly water).  Every material would be different, and what 
something 'weighs' in the environment, would be very different than it 
would weigh in a gravity field.

I have printed out some tables on magnetic susceptibilities.  If I know 
the strength of the magnetic field at the distance I select (in gauss or 
telsa units), what is the formula I would use to convert the magnetic 
susceptibilities into a g force factor or kilograms?

Assuming a spacecraft could withstand the radiation and other hazards, 
this magnetic zone could offer some fascinating material for science 
fiction stories.  For example, inside a colony, a balloon could be made 
out of a very small amount of ferromagnetic material such as iron.  Add a 
bit of electricity to iron to magnetize it, and lift would be increased 
astonishingly fast!
