Electromagnetic coils to manipulate micro/nano magnetic particles (Helmholtz and Maxwell)
Jan 2020 – Mar 2021
3D printed a holder to arrange 6 electromagnetic coils. Mounted 3D Helmholtz coils on a microscope stage
Applied DC voltage controlled via Labview and computer/electronic interfacing
The system was used to manipulate magnetic beads and also to move beads inside cells
Also, used MagnetiBox (as shown in Figure, 5 DOF) to apply various field frequency and amplitudes instead of custom made coils
