A linear generator which generates electric energy by reciprocal movement of magnets with inductive coils is provided. The linear generator has a plurality of elongate inductive coils, a plurality of magnets inserted into the respective inductive coils and slidable between two opposing ends of the inductive coils, a pulley assembly connected to top ends of the magnets, and an elevating motor generating and applying a lifting force to the magnets through the pulley assembly. The pulley assembly is operative to provide 1:N mechanical advantage, where N is preferably an even integer larger than 1. The pulley assembly is connected to the magnets by a plurality of rigid cables, rods, or strings, and a cable connected to the elevating motor is reeved through the pulley assembly, so as to exert a lifting force to the magnets via the pulleys.
