Hi Michael!
 
There is another explanation for the magnetism of a rock, than to be a
meteorite: the rock contains minerals which are magnetic. These minerals
or ore minerals are magnetic, because they are composed by iron or Ni! A
typical mineral (you can find in a lot of terrestrial rocks) is
magnetite. Magnetite is an iron oxide (Fe3O4) and many terrestrial
rocks can contain it in a amount, which is high enough, to make the rock
magnetic: for example: basalt or some metamorphites.
 
It?s not the fact of magnetism, what a rock makes to a meteorite, it?s
the complete mineral composition and the fabric of the rock. Your rocks
look like terrestrial pebbles or something like that
.but: the only way
to be sure is, to carry them to an expert
.
 
Best Wishes
 
Ingo
