Probing quantum mechanics, quantum aspects of general relativity along with the sensing and the constraining of classical gravity can all be enabled by unprecedented spatial sizes of superpositions of massive objects. In this paper, we show that there is a feasible setup sourced by realisable magnetic field gradients O(10 − 100) Tm−1 to construct a large spatial superposition of O(10−4 − 10−8) m for masses O(10−17 − 10−14) kg over a time period of up to 0.1 − 10 seconds.
