The correct answer is "Generator." A generator is a device that converts mechanical energy into electrical energy. To arrive at this answer, you could have eliminated the options that do not convert mechanical energy into electrical energy. The options "Magnet" and "Solar cell" do not convert mechanical energy; instead, magnets produce a magnetic field, and solar cells convert light energy into electrical energy. The remaining option is "Electric Motor," but electric motors convert electrical energy into mechanical energy. Therefore, "Generator" is the only option that correctly converts mechanical energy into electrical energy.
