Magnetic positioning of PC12 cells. a Schematic illustration of the magnetic manipulation. Cells were incubated with MNPs and seeded on a plate placed above a Hiperco 50A magnetic tip. b Simulation of magnetic field lines and intensity in Comsol software. The image presents a side view of magnetic flux density of tip. Red arrows represent field direction, intensity is color coded (low intensity in dark blue, high intensity in red). c Top view simulation of magnetic flux density 0.9 mm above magnetic tip (thickness of plastic plate culture). d Actual measurements of magnetic field produced by single tip. Error bars represent standard deviation (n = 3). e Graph representing the cell distribution throughout the plate
