Is iron always magnetic
Witryna2 paź 2024 · Magnets are materials that produce magnetic fields, which attract specific metals. Every magnet has a north and a south pole. Opposite poles attract, while like poles repel. While most magnets are made from metals and metal alloys, scientists have devised ways to create magnets from composite materials, such as magnetic polymers. WitrynaA permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. A magnetic force can be …
