10. 💡The heating Principle of Hair Dryers💡 

Hair dryers use wires made of materials like nickel-chromium alloy or iron-chromium-aluminum to convert electricity into heat. 🔌
Cold air passes over these heated wires via a fan inside the dryer, producing hot air. 🔥
Temperature controls prevent overheating, ensuring safe and effective drying and styling. 💨
