Answer:
It is the electromagnetic force which allows you to push a door closed, or to touch anything. Electromagnetism isn't just about magnets. It includes the common idea of like charges repel and opposite charges attract as well. Our hand is comprised of atoms, which are surrounded by electrons. Similarly for the door. As our hand gets closer and closer to the door, the electrons in the door's atoms and the electrons hand's atoms too get closer, and the repulsion force between the two increases significantly. This is what stops us from putting our hand through the door, and also what allows us to push the door open.
