Permanent magnets - Applications and perspectives

Permanent magnets have very promising prospects for increased use in many fields. The growth of the electric vehicle market, combined with the expanding share of renewable energy—particularly wind power—in electricity generation, continues to drive the growth of the permanent magnet market, especially for ferrite and Nd-Fe-B magnets.

Ferrite magnets are increasingly used in automotive locking and braking systems, as well as in electroacoustic systems such as speakers and microphones.

Nd-Fe-B magnets are increasingly used in electric and hybrid vehicles, as well as in wind power generation and information technology.

Alnico and Sm-Co magnets are used for specific applications due to their corrosion resistance and the stability of their magnetic properties at high temperatures, particularly in the aerospace and military sectors.

Sm-Fe-N magnets, which have recently emerged, are expected to see their applications expand into the same sectors as Nd-Fe-B magnets.

The study of permanent magnet applications covered in this report examines the various forms of energy conversion that can be achieved using these different types of magnets.
