Multiple layer coil windings on an electromagnet

I've started construction of a pretty hefty electromagnet but it is not strong enough and the answer is more windings (already running off a 36V golf cart battery charger) on my coil by winding multiple layers. My core is about an 18" x 1.5" dia rod and I have turned one layer of wire on it and it works awesome, but not awesome enough.

Novel design of a coreless axialflux permanentmagnet Multiple Layer Coil

Multiple layers of windings can reduce the space harmonics in the magnetomotive force of winding. The excitation of the coil is activated by the band on both sides by cutting the magnetic field of the magnet. Multiple layer windings have more band area ratio, and thus generate a Numerical Methods for Inductance CalculationPart 1 Elliptic Integrals. C) Multi-Layer Coils. Until now, we have dealt with single layer solenoid coils. However, Maxwell's elliptic integral formula for circular loops can be applied just as easily to coils consisting of multiple layers of windings. It's just a matter of calculating the mutual inductance between every pair of turns and taking the sum.

Optimization of a Two-Layer 3D Coil Structure with Uniform Multiple Layer Coil

Coil layers can be distinguished by their color; the first layer is shown in black and the second layer in red. Second coil layer is placed at a depth D 2 relative to the first coil layer, and it has narrower width W 2 compared to width of the first coil layer W. 3D coil structure has a length L with both coil layers folded to a depth D at the Multiple Layer Coil Stacked-Coil Technology for Compensation of Lateral Multiple Layer CoilA stacked-coil technology is demonstrated that realizes size-adjustable coil systems to compensate the notorious problem of lateral misalignment in nonradiative wireless power transfer (WPT) systems. The proposed system has a simple structure that consists of multiple layers of coils with various sizes. Depending on the misalignment, the coil pair that provides the best transfer efficiency is Multiple Layer Coil

Variable transformer with multi-layer coil - The Superior Multiple Layer Coil

If multiple layers of wire could be economically wound into a nearly perfect, sequentially-wound coil under the commutating surface, relatively more wire and less electromagnetic core material could be used for a given transformer capacity and would result in a smaller, more economical coil. What is a Fixed Inductor?Fixed inductors are a classification of inductors according to their structure, and fixed inductors are commonly used inductive devices. An inductor with a fixed inductance is called a fixed inductor (or a fixed coil), and it can be a coil with a single layer, multiple layers, honeycomb type, or a magnetic core. These coils are winded on the magnetic core using a wire of corresponded diameter Multiple Layer Coil

When compared with the single-layer coil design, the only difference for a multiple-layer coil design is that the design variables are located on additional design surfaces. When a computational domain is meshed so that the design surfaces coincide with the mesh edges, the design variables can be specified on these surfaces directly.
