Magneettikehä
Magneettikehä, often translated as magnetic ring, is a term used in physics and engineering to describe a closed loop or toroid structure made of magnetic material. This structure is designed to contain and guide magnetic flux lines. The primary purpose of a magneettikehä is to concentrate magnetic fields, minimizing flux leakage into the surrounding environment. This concentration is crucial for efficient operation of various electromagnetic devices.
These structures are commonly found in transformers, where they form the core that couples the primary and
The materials used for magneettikehä vary depending on the application. Soft magnetic materials, such as ferrite
