I already have detailed winding diagrams, coil counts, wire gauges, and a full wiring schematic for three compact electromagnets—each under 10 cm in any direction. Your task is to turn these drawings into a tangible proof-of-concept and ship it to me. The magnets will sit in a custom harness. I’m leaning toward a light alloy or other metal solution, but I’m open to your recommendations once you see the design constraints. All electronic components, fasteners, and raw materials will be reimbursed at cost; please keep receipts. Power can come from batteries, a small AC supply, or a rechargeable pack—I’m happy with whichever option best matches your workshop setup and meets the performance targets we’ll discuss. Deliverables • Three fully wound, insulated, and terminated electromagnets built to the supplied spec • Matching harness, machined or fabricated to precise dimensions, ready for mounting • Basic bench test results: resistance, current draw, and pull force at the chosen voltage • Photos or a short video showing operation prior to shipment • Secure packaging for safe delivery Once this prototype meets the agreed-upon metrics, there’s a larger program waiting, so flawless craftsmanship and clear documentation are essential. I look forward to collaborating and seeing these magnets spring to life.

Your winding diagrams, coil counts, wire gauges, and a full wiring schematic for three compact electromagnets under 10 cm each grab my attention. I recently prototyped and delivered a 3-magnet assembly with validated winding, harness fit, and bench-test readiness. Plan: assess harness interfaces, select a suitable light-alloy frame, and set up a concise test protocol (resistance, current draw, pull). What scope or timeline details would you like clarified to align on acceptance criteria? Could you confirm the target pull force per magnet and the acceptable test voltage and measurement method so I tailor winding/specs accordingly? Portfolio: https://www.freelancer.com/u/markoa7.

The risk is achieving the specified magnetic field strength with the given winding diagrams and wire gauges within the tight physical constraints. I'll handle this by meticulously following your winding diagrams, ensuring consistent tension and insulation during the winding process using a precision winding machine, and terminating the coils with appropriate connectors. This will result in three functional electromagnets built to your exact specifications. I will use AutoCAD to verify the physical dimensions against your designs before fabrication. What material are you prioritizing for the custom harness, and what are the environmental conditions it needs to withstand? I need your confirmation on the harness material before I can source components and start building. I have a 5.0 rating across 10 reviews on here, and Preferred Freelancer status.

⚙️ Electromagnet Prototype Fabrication & Custom Harness ⚙️ I can help turn your existing winding diagrams and wiring schematic into three physical electromagnet prototypes built to the supplied specifications. Since you already have the coil counts, wire gauges and winding details defined, I would focus on accurate fabrication, insulation, termination, mechanical fit and repeatable bench testing rather than changing the electrical design without a clear reason. I would first review the drawings and dimensions to understand the winding method, core/material requirements, termination points and mounting constraints. For the custom harness, I can evaluate the available space and recommend a practical metal or lightweight alloy construction that provides the required rigidity and precise mounting while keeping the assembly compact. Each electromagnet would be checked for winding quality, insulation and electrical continuity before testing. I can document resistance and current draw at the agreed test voltage and measure pull force using suitable bench-test equipment. I would also photograph or record the completed assemblies and their operation before carefully packaging them for shipment. I’d be happy to review the winding diagrams and full schematic first, confirm the fabrication approach, required tolerances and testing criteria, and then proceed with the three-prototype build.
