Magnetic Grapples are short-ranged "hooks" created ethereally by a magnetic field. The idea is to attach the grapple to something with a ferrous composition and depending on the field polarity, push or pull the object. This effect can be useful as an effective weapon as accuracy is extremely high, and occasionally has other uses in general space exploration.
