SUMMARY
The optimal material for electromagnet bobbins and end caps is crucial for performance. Steel washers, while strong, can adversely affect the electromagnetic field and may retain magnetism after current cessation. In contrast, nylon washers, when affixed to the iron core using industrial epoxy, do not interfere with the electromagnetic field and prevent residual magnetism. Therefore, nylon is the recommended choice for bobbin materials in electromagnet designs.
