Definitions
- Our invention relates to magnetic cores for use as a magnetic switching element for controlling core storages, and particularly to a process of making the same.
- magnetic cores When magnetic cores are used as storage elements or magnetic switching elements, it is desirable to restrict, as far as possible, the appearance of eddy currents. Consequently, such cores are usually constituted of soft-magnetic, oxidic materials, which, as is known, have a very low electrical conductivity.
