Magnetic machines are devices that utilize magnetic fields to perform various functions, such as generating electricity or moving objects. They often rely on the principles of electromagnetism, where electric currents create magnetic fields. Common examples include electric motors and generators, which convert electrical energy into mechanical energy and vice versa. These machines can be found in many everyday applications, from household appliances like refrigerators to industrial equipment. They play a crucial role in modern technology, enabling efficient energy use and automation in various sectors, including manufacturing and transportation.
