Could that be a meteorite?
I suppose it could be. Looks kinda like one. Most of them that make it to the ground are highly metallic, and it looks like it has some characteristics of melting.
Could also be from a lightning strike, I suppose. But that would have been on sand, and can then create a glassy piece of sand, that wouldn't be magnetic. Perhaps you should take it to a college science department to have it analyzed. Very interesting!
Thanks for that.
