A friend tell you that a refrigerator door beneath it's layer of white painted plastic, is made of aluminum. How could you check to see if this is true withoutscraping away the plastic?
What do refrigerator magnets stick to?
To check if a refrigerator door is made of aluminum without scraping away the plastic, you can use a simple magnetic test. Here's how you can do it:
1. Obtain a refrigerator magnet: Most refrigerator magnets are made of ferrite or neodymium, which are attracted to ferromagnetic materials, such as iron or steel.
2. Approach the magnet to the surface of the refrigerator door: Carefully bring the magnet close to different areas of the door, including the edges and corners. If the magnet is strongly attracted to the door, it suggests that the door contains a ferromagnetic material like steel. If there is little or no attraction, it could indicate that the door is made of a non-magnetic material like aluminum.
It's important to note that this test is not foolproof as some refrigerator doors can have layers of different materials. However, if the magnet doesn't strongly stick to any part of the door, it is more likely that the door is not made of aluminum.
Remember, using a magnet works because aluminum is not attracted to magnets, while steel and iron are.
