  The statistical properties of the subgrid energy transfers of homogeneous
small-scale dynamo are investigated during the kinematic, nonlinear and
statistically saturated stages. We carry out an a priori analysis of data
obtained from an ensemble of direct numerical simulations on $512^3$ grid
points and at unity magnetic Prandtl number. In order to provide guidance for
subgrid-scale (SGS) modelling of different types of energy transfer that occur
in magnetohydrodynamic dynamos, we consider the SGS stress tensors originating
from inertial dynamics, Lorentz force and the magnetic induction separately. We
find that all SGS energy transfers display some degree of intermittency as
quantified by the scale-dependence of their respective probability density
functions. Concerning the inertial dynamics, a depletion of intermittency
occurs in presence of a saturated dynamo.
