Can aluminum and copper be attracted by magnets?
1. The property of attracting substances such as iron, cobalt, nickel, etc. is called a magnet. The two ends of the magnet are magnetic poles, one end is north pole (N pole), and one end is south pole (S pole)
2. The same magnetic poles are mutually exclusive, and the opposite magnetic poles attract each other. This is how the magnet works.
3. There are many magnets with two magnetic poles in the iron. When the external force of the magnetic field acts, the internal arrangement of these magnets is disordered and non-magnetic. When the iron is brought close to the magnet, the original magnets are neatly arranged under the action of the magnet, so that one end close to the magnet has a polarity opposite to the polarity of the magnet and attracts each other. This means that the iron can be magnetized by the magnet due to the presence of the original magnet. Metals such as copper and aluminum have no original magnet structure and cannot be attracted by magnets.
