How are artificial magnets created and who created them?

Dear Student
An artificial magnet is a magnetized piece of iron (or other magnetic material). Artificial magnets are required because natural magnets have odd and irregular shape and they are not magnetically very strong. Artificial magnets can be given desired shape and made very strong.
Artificial magnets can be created by doping iron, nickel, and/or cobalt with other elements or by induction.
A magnet that is prepared artificially form the artificial magnets. Examples include an electromagnet, a magnetic needle, horseshoe and bar magnets etc.
