is it? i didn't upload the jar yet, only the attachment cos it is still unfinished.
i am still working on it.

but i just reuploaded 02 version on the first post in case you are looking at that one.

i managed to work 2 bar magnets now,

i will try to have no magnet( not working) , one magnet(seems to work) , 2 bar magnet (working ).

i am working on the magnet field only, the compass is not correct yet because i wanted to show the magnet inside as a uniform magnetic field of 225T which the original wolfgang and paco version shows as a large uniform magnetic field due to short distance to any of the dipoles.

will fix the compass after i figure out the field part.
