How to Make a Magnetic Coil DoItYourself

A magnetic coil is made using a conductor, generally an insulated copper wire, and winding it around a core to produce an inductor, or a magnet. Basically, a wire that has electricity running through it produces a magnetic field. However, using a single wire would only generate a very faint field. How to Make a Magnetic Coil DoItYourselfRemember that the more the coil is tightly spaced together, the better and stronger its magnetic force will be. Then set aside approximately 6 to 7 inches of wire dangling at the end of the core. Proceed to wrap all the way to the other side of the core. Step 3 - Adhere the Coil to the Core. Using glue or tape, adhere the coil to the core.
