Intersecting M-branes

We present the magnetic duals of Güvenʹs electric-type solutions of D = 11 supergravity preserving 14 or 18 of the D = 11 supersymmetry. We interpret the electric solutions as n orthogonal intersecting membranes and the magnetic solutions as n orthogonal intersecting 5-branes, with n = 2, 3; these cases obey the general rule that p-branes can self-intersect on (p − 2)-branes. On reduction to D = 4 these solutions become electric or magnetic dilaton black holes with dilaton coupling constant a = 1 (for n = 2) or a=13 (for n = 3). We also discuss the reduction to D = 10.
