Iron does not make permanent magnet because retainity of iron magnetic is low. Iron can be easily magnetized but not permanent
The properties of magnetic materials can be derived from their hysteresis loop which is a curve obtained by applying an alternating magnetic field to the material under test and measuring its magnetization vs. the magnetic field.
Two very important parameters are the remanence and coercitivity.
Nd2Fe14B is use for permanent magnetic
Neodymium magnets can be more expansively called Neodymium-Iron-Boron magnets for their composition. They are the strongest of permanent magnets per unit mass at this time, and their strength comes from the rigidity and stability of the domain walls.
just simply electricity pass throw the any material then it produced magnetic field,
set up to make electricity pass on material
hope it help
