Abstract
A composite permanent magnet comprises a first phase including a magnetically hard material and a second phase including a magnetic material. Each of the materials has an anisotropy value selected such that a ratio of the values falls within a predefined range and a resulting grain size of the magnetic material is greater than a predefined threshold defined by the predefined range.
