Within the framework of general relativity, the properties of the local space-time of fermions with an electric charge are considered. It is well known that the Dirac spinor field acts locally, as a contact spin-spin interaction of the gravity and spinor fields that may lead to some specific properties of spacetime structure. It is shown that this interaction causes real rotation of particles with spin ħ/2. It was found that this rotation is a source of intrinsic magnetic moment for electrically charged particles. In this case, it was found that the local spacetime of charged particles can have the spacetime structure of a possible wormhole.
