I walked through a Missouri cave in 1970 that had a spot where metal was stuck to a rock round head high. I’ve tried to look up that local feature, but can’t find an article about it. Am I searching it the right way? I think it was mid Missouri or south near Branson. I’m in Eldon.

The needle of the compass is magnetic. So the needle is attracted to the iron oxides. Did you try cobalt or nickel? Are there any other ores that are also attracted to a magnet even weakly like some forms of iron pyrite or titanium oxide? How about paramagnetic or repulsive (yeah, forgot the term) in a magnetic field like copper, aluminum?

I do not have any Co or Ni minerals that do not also have Iron... so I am not sure about that... Yes there are minerals that are weakly magnetic (hematite is a good example) that is were a sensitive compass is particularly useful. Regarding di or paramagnetism... not sure how to test this. Keep in mind repulsion is tricky because similar poles repel.... so if your mineral repels another magnet, it will likely attract by simply flipping it around.

سلام بزرګوار من يک سنګ دارم که رنګش سیاه است و ساعت دستی را توقف ميکند و جنراتور را خاموش ميکند و قاغذ را که دورش کنیم و سګرت ليتر را برايش بګيريم آتش نميګيره و نميسوزه ايا شهاب سنګ است اميدوارم که جوابش را بګويد تشکر

Abdul, I am afraid my lack of knowledge of your language and Google translate has left me confused... can you try and translate your question?
