Spiral coils are elongated, helical structures that can be found in various applications, from mechanical devices to electrical components. They are often made from materials like metal or plastic and are designed to store energy, provide tension, or create resistance. Common examples include springs and the coils in electromagnetic devices. In nature, spiral coils can also be observed in the shape of certain shells and plants, showcasing a pattern that is both efficient and aesthetically pleasing. The design allows for compact storage of energy or materials, making spiral coils a versatile solution in engineering and design.
