Using a novel magnetic quadrupole trap based on strong permanent magnets, we trap a 70 mK sample of ground-state OH molecules produced by a Stark decelerator. The trap center lies only 1 cm from the decelerator exit which enables a trapped molecule density of 10$6$ cm$\mathrm{<mrow\; data-mjx-texclass="ORD">-3</mrow>}$. Our magnetoelectrostatic trap (MET) design allows for the addition of an electric field of variable magnitude to the trapped sample to facilitate polar-molecule collision studies. We report progress toward collisional studies between trapped OH molecules and different atomic and molecular beams.
