A localized magnetic field is a vector field that alters in space because of magnetic materials or
electric currents. Some examples of localized magnetic fields are indoor localization, magnetic
anomaly detection, magnetoencephalography, and quantum physics. Magnetic fields can be used
to estimate the orientation and position of a device inside a building by measuring the changes in
the magnetic field caused by ferromagnetic substances. On the other hand, a Tri-hybrid nanofluid
can transfer heat better than a normal hybrid nanofluid by mixing three different nanoparticles
with synergistic effects. It can have more varied physical and thermal properties by choosing
different combinations of nanoparticles. That’s why it has more possible uses in various fields
such as solar thermal, biomedical, and industrial processes. Therefore, the goal of this research is
to explore the complex dynamics of the localized magnetized force that affects the rotation of
nanostructures and the vortex formation in the tri-hybrid nanofluid flow regime using the single-
phase model, while the governing partial differential equations are discretized numerically. With
the help of our self-developed computer codes in MATLAB language, we intend to understand the
way these parameters affect the flow and thermal properties of the nanofluids. Additionally, the
current work provides a novel analysis that makes it possible to investigate the flow lines and |
