5. Use of a magnet is a practical approach to determine whether or not a car door is metallic or non-metallic (like plastic). If the magnet shows any form of attraction or repulsion with the door, it contains considerable metal parameters. If it doesn't show attraction or repulsion, a necessarily greater portion of the door is made of plastic or comparable non-metallic substances. 6. The Magnet tends to stick to objects (like a refrigerator door) with a strong preference for iron, cobalt, nickel. The observation that the magnet sticks to the refrigerator door but does not stick to a certain nail likely suggests that the nail isn't made of aforementioned metals or has a painted/coated surface that weakens its magnetic properties. If not that, it might be the lack of magnetic strength concerning the weight of the nail.
Explanation
5. To plan an investigation to determine if a car door is made of a nonmagnetic material, such as plastic, one needs to use a reasonably powerful but small magnet. Here are the steps: - Grip the magnet - Slowly bring the magnet closer to the car's door - If a statue of repulsion or attraction is observed, the material is metallic (and possibly iron-based). If not, the material is likely not metallic (Free of iron) and one can end there determining that the car door may consist of a considerably high amount of non-metric material like plastic.6. Magnets stick to objects that have magnetic material which is mostly metals like iron, cobalt, nickel. Since the magnet sticks to the refrigerator door, it indicates that the door contains magnetic material and is metallic. Given the nail doesn't stick anyway indicates that it might not be made of iron, nickel, or cobalt- or it might be that the nail is painted/surface coated causing hindrance with the magnetic attraction Or, probably, the magnet used is not strong enough to trigger magnetic attraction given the weight profile of the nail.
