Simple Magnetic Overunity Toy

The term "Simple Magnetic Overunity Toy" typically refers to a concept or device that allegedly demonstrates overunity, which is a term used in the context of energy systems that supposedly produce more energy output than input. These devices often claim to use magnets in a way that seemingly allows them to operate indefinitely without a net energy loss, defying established laws of physics, particularly the First and Second Laws of Thermodynamics.
