antecedent

(=> (and (instance ?EM Electromagnet) (instance ?T Transfer) (instance ?E Electricity) (objectTransferred ?T ?E) (path ?T ?EM)) (exists (?M) (and (instance ?M Magnetism) (instrument ?M ?EM))))	Cars.kif 3878-3888	If an object is an instance of electromagnet and a transfer is an instance of transfer and another object is an instance of electricity and the object transferred in the transfer is the other object and the object is path along which the transfer occurs, then there exists a process such that the process is an instance of magnetism and the object is an instrument for the process
(=> (and (instance ?EM Electromagnet) (not (holdsDuring ?T1 (exists (?T ?E) (and (instance ?T Transfer) (instance ?E Electricity) (objectTransferred ?T ?E) (path ?T ?EM)))))) (not (holdsDuring ?T1 (exists (?M) (and (instance ?M Magnetism) (instrument ?M ?EM))))))	Cars.kif 3890-3906	If an entity is an instance of electromagnet and there exist another entity and a third entity such that the other entity is an instance of transfer and the third entity is an instance of electricity and the object transferred in the other entity is the third entity and the entity is path along which the other entity occurs doesn't hold during the other entity1, then there exists a fourth entity such that the fourth entity is an instance of magnetism and the entity is an instrument for the fourth entity doesn't hold during the other entity1
