Hello, You need a battery-powered electromagnet for a consumer electronics project with strong field, small size, and efficient power use. I will design a compact coil and magnetic circuit matched to your battery and space constraints, and pair it with an efficient drive that keeps currents low without sacrificing field. My approach: 1) set target field at the working distance, 2) choose core, coil geometry, and insulation to hit weight limits, 3) design a low-loss drive using PWM and high-efficiency MOSFETs with proper thermal paths, 4) build a prototype and test field strength, current, and temperature, 5) deliver a production-ready coil assembly, PCB layout, and a simple test protocol. I have hands-on experience in embedded systems, electrical engineering, circuit design, PCB layout, and product development for consumer devices. I can share examples of similar battery-powered coils and qualifications when we discuss targets. What is the target magnetic field strength at the critical operating distance, and the acceptable tolerance? What are the available battery type, capacity, and max continuous current? Any thermal limits? What are the size, weight, and mechanical integration constraints for the electromagnet assembly? What regulatory or safety requirements should we meet (EMI, safety, RoHS, etc.)? Do you want the deliverables to include production-ready PCB layout, enclosure design, BOM, and a test protocol, or just the magnet coil and driver? Best regards,
