## 3 Results  
The effects of a magnetic field, mass transpiration, and Navier's slip on the flow of incompressible viscous fluid with CNT are examined. Using the appropriate similarity transformations for velocity and temperature, the system of PDEs is transformed into a system of nonlinear ODEs with constant coefficients. The analytical solution for the velocity profile is then obtained in exponential form, whereas the analytical solution for the concentration field was produced via the Laplace transformation in terms of an incomplete gamma function. Different graphs for the CNT are used to assess the consequences of the problem. The advantages of adopting MHD for its applications in industry and medicine are discussed, as well as a model of MHD nanofluid flow over a stretching/shrinking surface. Figure 2 depicts the variation in transverse velocity with different values of \(M\) for the suction case and keeping all other parameters constant as shown in the figure. Demonstrating that the transverse velocity decreases as \(M\) increases on the stretching surface, MWCNT nonfluids have higher effective velocities than the SWCNT-deferred nanofluids, and this might assist in industrial applications and medical benefits. Earlier research tells us that carbon nanotubes are likely quicker than nanoparticles in achieving the same tumour instance. As a result, in the presence of CNTs or nanoparticles, the magnetic field can also act as a source. We notice that the SWCNT Nanofluids are better nanofluids than the MWCNT Nanofluids. We study from these final results that the usage of CNTs in most cancerous therapies can be more useful than all sorts of nanoparticles. Figure 3 portrays the variation in axial velocity with different values of \(M\) for the suction case and keeping all other parameters are constant as shown in the figure. It is helpful that in the stretching surface, the transverse velocity decreases as \(M\) increases. Due to the development of the Lorenz force, the velocity boundary layer will decrease as the magnetic field increases. For both circumstances, transverse velocity increases fast at first and then remains constant after a certain value of \(\eta\), whereas axial velocity falls exponentially at first and then reaches zero after a certain value of \(\eta\). Figure 4 shows the impact of the \(\varphi\) on the axial velocity for stretching/shrinking sheet. From this figure, it is clear show that velocity increases with increasing the value of the \(\varphi\) parameter and also \begin{table}
