Nonmetals are poor electrical conductors but they are considered as good insulators. Among the given statement, the most likely reason that nonmetals are electrical insulators is that since valence shells in nonmetal atoms are almost full, the atoms attract electrons and hold them tightly to fill their valence shells.
Magnet can, like any object with a mass, exert gravity force on different objects, regardless of their magnetic properties. Same goes for electric force if magnet is charged and mechanical force. The latter can be easily observed when a magnet falls on somebody's foot (which is, in most cases, non-magnetic
