  We present a holographic perspective on momentum transport in strongly
coupled, anisotropic non-Abelian plasmas in the presence of strong magnetic
fields. We compute the anisotropic heavy quark drag forces and Langevin
diffusion coefficients and also the anisotropic shear viscosities for two
different holographic models, namely, a top-down deformation of strongly
coupled $\mathcal{N} = 4$ Super-Yang-Mills (SYM) theory triggered by an
external Abelian magnetic field, and a bottom-up Einstein-Maxwell-dilaton (EMD)
model which is able to provide a quantitative description of lattice QCD
thermodynamics with $(2+1)$-flavors at both zero and nonzero magnetic fields.
We find that, in general, energy loss and momentum diffusion through strongly
coupled anisotropic plasmas are enhanced by a magnetic field being larger in
transverse directions than in the direction parallel to the magnetic field.
Moreover, the anisotropic shear viscosity coefficient is smaller in the
direction of the magnetic field than in the plane perpendicular to the field,
which indicates that strongly coupled anisotropic plasmas become closer to the
perfect fluid limit along the magnetic field. We also present, in the context
of the EMD model, holographic predictions for the entropy density and the
crossover critical temperature in a wider region of the $(T,B)$ phase diagram
that has not yet been covered by lattice simulations. Our results for the
transport coefficients in the phenomenologically realistic magnetic EMD model
could be readily used as inputs in numerical codes for magnetohydrodynamics.
