Nkọwa dị mkpirikpi:

Bonded NdFeB, nke Nd2Fe14B mejupụtara, bụ ihe ndọta sịntetịt.Ọ bụ ihe ndọta emere site na ịgwakọta ntụ ntụ magnetik NdFeB emenyụ ngwa ngwa na ihe nkedo site na “mkpụzi mkpakọ” ma ọ bụ “ịkpụzi injection”.Ihe ndọta NdFeB etinyere na neodymium akpụ akpụ ntụtụ bụ ihe a na-ejikarị n'etiti ha.
