Abstract
This article examines a wire coating technique that considers how viscoelastic Eyring–Powell fluid is studied with magnetohydrodynamic (MHD) flow, thermal transfer, and Joule heating effects. Temperature-dependent variable and flexible viscosity models are considered. The interface boundary layer equalities which describe flux and thermal convective phenomena are evaluated using a dominant numerical technique—the so-called Runge–Kutta 4th-order method. A permeable matrix which behaves like a dielectric to avoid heat dissipation is taken into account and is the distinguishing aspect of this article. The effect of thermal generation is also explained, as it controls power. The effects of various parameters, such as non-Newtonian fluid, magnetic field, permeability, and heat source/sink, on wire coating processes are investigated through graphs and explained in detail. For the sake of validity, numerical techniques are compared with a semi-numerical technique (HAM) and BVPh2, and an outstanding agreement is found.

Summary
Water, and other lubricants are considered to be non-Newtonian fluids in science and engineering technologies. Non-Newtonian behavior exists in different liquid materials like glue, paint, ketchup, custard, and Crystals 2020, 10, 168; doi:10.3390/cryst10030168 www.mdpi.com/journal/crystals. Because of their vast and significant uses in industry, petroleum and chemical engineering, and in other fluid mechanics, they have gained the attention of researchers [1–8]. Ellahi et al [9] discussed the non-Newtonian micropolar liquid in blood movement over a composite stenosis. Many important features of Eyring–Powell fluid are discussed by researchers [10–14]. Wire coating techniques are very important as they can help avoid injury and decrease losses which may be generated by machine oscillation. Various liquid polymers are used in wire coating processes.
