Abstract (en)
In a magnetic core having a body (1) of polycrystalline magnetic ceramic and one or more gaps (2) of composite magnetic material, the latter is formed of polycrystalline magnetic ceramic platelets which are embedded in a dielectric binder and which are oriented so that their main faces are parallel to the magnetic field to which the core is to be subjected. Also claimed are an inductor and a transformer including the above core.
