Size Performance of the Attractive Force for a Dental Magnetic Attachment.

Why are magnetic attachments popular in Japan and other Asian countries?

“…To increase the attractive force, the size of the Sm-Co magnet must be increased. The neodymium magnet (neodymium-iron-boron-alloy) has a much more attractive force [30]. Notably, the magnetic structures of materials have been improved by research with finite element analysis [31].…”
