Measurements
Ring magnets of ferrite are used for the construction of speakers, for example, or to build self-made levitation magnets. They help picking needles or screws out of garbage or have their places in analytic systems. Rings are mostly magnetised through their thickness.
Ferrites are usually non-conductive ferrimagnetic ceramic compounds derived from iron oxides such as hematite (Fe2O3) or magnetite (Fe3O4) as well asoxides of other metals. Ferrites are, like most other ceramics, hard and brittle. In terms of their magnetic properties, the different ferrites are often classified as "soft" or "hard", which refers to their low or high magnetic coercivity.
