graphene is very diamagnetic. pyrolytic graphene as well. are ufos made of pyrolytic graphene?

Diamagnetic materials are repelled by a magnetic field; an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force. In contrast, paramagnetic and ferromagnetic materials are attracted by a magnetic field
