One possible answer could be that being able to turn the electromagnet on and off allows for control over its magnetic field. This control can be used in various applications such as lifting objects, switching electrical circuits, or generating mechanical motion. Being able to turn off the electromagnet also allows for conserving energy and preventing overheating.
