Abstract: A magnet material of an embodiment includes a composition represented by a formula 1: (Fe1-x-yCoxTy)2(B1-aAa)b, and a metallic structure having a CuAl2 crystal phase as a main phase. T is at least one element selected from V, Cr, and Mn. A is at least one element selected from C, N, Si, S, P, and Al. An atomic ratio x of Co and an atomic ratio y of the element T satisfy 0.01≦y≦0.5 and x+y≦0.5. When the element T includes at least one element selected from V and Cr, a total atomic ratio of V and Cr is 0.03 or more. When the element T includes Mn, an atomic ratio of Mn is 0.3 or less. An atomic ratio a of the element A satisfies 0≦a≦0.4. A total atomic ratio b of B and the element A satisfies 0.8≦b≦1.2.
