  Magnetic hopfions are localized magnetic solitons with a nonzero 3D
topological charge (Hopf index). Herein, an analytical calculation of the
magnetic hopfion gyrovector is presented and it is shown that it does not
vanish even in an infinite sample. The calculation method is based on the
concept of the emergent magnetic field. The particular case of the simplest
nontrivial toroidal hopfion with the Hopf index $\|Q_H\|=1$ in the cylindrical
magnetic dot is considered and dependencies of the gyrovector components on the
dot sizes are calculated. Nonzero hopfion gyrovector is important in any
description of the hopfion dynamics within the collective coordinate Thieles
approach.
