Motivated by recent experiments, we investigate the quantum spin Hall statein 2D topological insulator/ferromagnetic metal planar junctions by means of atight-binding model and linear response theory. We demonstrate that whether theedge state Dirac cone is submerged into the ferromagnetic subbands and thedirection of the magnetization dramatically affect (i) how the edge statepercolates into the ferromagnet, and (ii) the spin-momentum locking of the edgestate. Laminar flows of room temperature persistent charge and spin currentsnear the interface are uncovered. In addition, the current-induced spinpolarization at the edge of the 2D topological insulator is found to bedramatically enhanced near the impurities. The current-induced spinpolarization in the ferromagnet is mainly polarized in the out-of-planedirection ${\hat{\bf z}}$, rendering a current-induced spin torque that ispredominantly field-like $\propto {\bf S}\times{\hat{\bf z}}$.
