Abstract

A magnetic material of an embodiment includes: first magnetic particles that contain at least one magnetic metal selected from the group including Fe, Co, and Ni, are 1 μm or greater in particle size, and are 5 to 50 μm in average particle size; second magnetic particles that contain at least one magnetic metal selected from the group including Fe, Co, and Ni, are smaller than 1 μm in particle size, and are 5 to 50 nm in average particle size; and an intermediate phase that exists between the first magnetic particles and the second magnetic particles.
