The material selected for making a permanent magnet should have:

Step-by-step solution

For a material to be used as a permanent magnet, it must possess the following properties: High retentivity: This ensures that the magnet is strong and retains a large amount of magnetization even after the external magnetizing field is removed. High coercivity: This ensures that the magnetization is not easily erased by stray magnetic fields, temperature fluctuations, or minor mechanical damage. High permeability: This allows the material to be magnetized easily and strongly when exposed to a magnetizing field. Th
