Ferrite ceramics and ferromagnetic materials are often produced as powder, which can be sintered into solid cores. Ferrite cores are used in electronic inductors, transformers, and electromagnets ...

With inductors, coils and chokes, air cores result in the least inductance ... The most popular are iron (or iron alloys, laminations, or powder); and ferrite, a black, nonconductive, brittle magnetic ...

The inductors market is segmented by type into air core inductors, iron core inductors, ferrite core inductors ... which use air as the magnetic core material, are particularly useful in high ...

This magnetic read-only memory (ROM), contrary to ordinary coincident-current magnetic core memories (used for RAM), uses the ferrite cores as transformers. If you look at the picture above ...
