Re: What do the magnetic field lines look like for mobius strip magnet?

     Hmmm!?  That is an interesting question.  You can make a Mobius 
strip magnet rather eaaily out of rubber magnet sheet.  You need the kind 
that is uniformly magnetized rather than the common kind that has a 
pattern recorded in it.  That sheet stock is readily available on the 
web.  One place is Magnum Magnetics.  You can cut a strip perhaps an inch 
wide and a foot long and glue the ends together to make the Mobius 
strip.  
     You can get an idea of what the field looks like using MagneView 
sheet.  That is also available on the web.  Beautiful Magneview patterns 
are shown in the neat book Mondo Magnets.  It is available on the web.
     It is possible to compute the fields using one of the big finite 
element computer programs but it would be diffucult and very expensive.
 
Good Luck
