Look test: Look for wear spots that indicate that silver plate has worn off from the base metal. Signs he regrets hurting you. These are the only pure metals that can be turned into a permanent magnet. A magnet is any object that produces its own magnetic field that interacts with other magnetic fields. You can only show that an object is a magnet if it repels another magnet, Home Economics: Food and Nutrition (CCEA). How do you know if a something is a magnet. This is called induced magnetism. 4 Opposite (unlike) poles attract, and like poles repel. If these metals have not been turned into a permanent magnet they will still be attracted to a magnet if placed within a magnetic field. Magnets repel and attract other magnets, and attract magnetic substances. Two magnets trapping a piece of intestine between them can appear as one magnet when one magnet is behind the other in an x-ray picture. If the domains fall into disorder, the individual fields cancel out, leaving the magnet weak. Read about our approach to external linking.
