  We investigate the viability of dipole-dipole interaction as a means of
entangling two distant ferromagnets. To this end we make use of the Bogoliubov
transformation as a symplectic transformation. We show that the coupling of the
uniform magnon modes can be expressed using four squeezing parameters which we
interpret in terms of hybridization, one-mode and two-mode squeezing. We
utilize the expansion in terms of the squeezing parameters to obtain an
analytic formula for the entanglement in the magnon ground state using the
logarithmic negativity as entanglement measure. Our investigation predicts that
for infinitely large two-dimensional ferromagnets, the dipole-dipole
interaction does not lead to significant long-range entanglement. However, in
the case of finite ferromagnets, finite entanglement can be expected
