How does the magnetic permeability of cast iron limit its use in certain animal sculpture installations?

Cast iron is a popular material for sculptures due to its durability and cost-effectiveness. However, its high magnetic permeability can pose challenges in certain animal sculpture installations. Magnetic permeability refers to a material's ability to support magnetic fields, and cast iron's high permeability makes it susceptible to electromagnetic interference. This can lead to unwanted attraction or repulsion in environments with strong magnetic fields, such as near electrical equipment or in public spaces with high-tech infrastructure. Additionally, the magnetic properties may cause corrosion or structural instability over time, limiting its use in large-scale or outdoor animal sculptures. Artists often opt for alternative materials like bronze or stainless steel to avoid these issues, ensuring longevity and artistic integrity. Understanding these limitations helps in selecting the right material for durable and visually appealing animal sculptures.
