To understand the correct parameters dictating the de-encapsulation, we first identify a critical height, hcr, shown in Figure . hcr is defined as the critical distance between the center of mass of a MNLD and the top of the magnet stack, such that the buoyancy force on the drop balances magnetic force acting on the drop. Let us define the drop release height, hdr, as the distance between the MNLD (when released into the fluid medium) and the top of the magnet stack. If the drop is so released that hdr > hcr, the buoyancy force on the drop dominates, and the drop moves upward till it reaches the free surface [see Figure ]. If the drop is so released that hdr < hcr, the magnetic force dominates, and the drop moves downwards in the direction of increasing magnetic field strength [see Figure ]. This is the domain (i.e., the domain corresponding to hdr < hcr) where the parametric study has been conducted. In this experimental domain (i.e., hdr < hcr), two separate cases were observed. In the first case, the magnetic field induced aggregates (present inside the drop) ensured that the drop gets pushed downwards to the base, with the drop getting deformed [see Figure ] and eventually ending up wetting the base of the container without losing any of the contents (i.e., without any de-encapsulation). In the second case, the aggregates, which are formed by the presence of the magnetic field acting on the NPs present inside the drop, again ensure that the drop is pushed downwards, gets deformed considerably until reaching a critical point. At this critical point, a portion of the nanoparticles (in the form of an aggregate), along with some attached water molecules, get pulled out of the drop. This is the phenomenon of complete de-encapsulation, where this nanoaggregate comes out of the drop entirely and loses any contact with the drop. This de-encapsulation occurs at the tip of the deformed drop and the released nanoaggregate settles at the base of the container [as shown in Figure . The drop after partially losing its contents via de-encapsulation might either go downwards or upwards. For example, the drop will go downwards and settle at the same location on the base of the container where the released nanoaggregate has deposited, if the drop, even after the de-encapsulation, contains enough NPs to experience large enough magnetic force that overwhelm the vector sum of buoyancy, viscous drag forces [see Figure ]. On the other hand, if after de-encapsulation, the drop no longer contains sufficient MNPs, the magnetic force on the drop becomes weak enabling the buoyant and viscous forces to drive the upwards and away from the base [see Figure . For either of the scenarios, there is no permanent deformation of the drop. Here, we define a quantity called the de-encapsulation distance, hde, which is the distance from the de-encapsulation point to the top of the magnet stack [see Figure , Figure ]: the de-encapsulation point can be defined as the spatial coordinate at which the aggregate separates completely from the MNLD.
