Tin: Non-Magnetic Metal with Valuable Properties
2024.9.24 Tin is a non-magnetic metal, meaning it does not possess the ability to attract or repel other magnets or magnetic materials. This is because tin lacks unpaired electrons in its atomic structure, a characteristic necessary for magnetism. Despite its non-magnetic nature, tin is of interest in the field of materials science due to its other valuable properties, such as its
