Magnetic Plug

thingiverse

Creating a four-wire magnetic plug requires several steps. Begin by gathering materials including a metal rod, copper wire, and electrical tape. The first step is to shape the metal rod into a plug form using pliers. Next, wrap the copper wire around the metal rod in a spiral pattern, making sure to leave enough space for the wires. Cut the excess wire with scissors and strip the ends of the wires using wire strippers. Use electrical tape to secure the wires in place, ensuring they are snug against the plug body. Finally, test the plug by connecting it to a device and verifying that the magnetic field is strong enough to detect.
