How to Receive Cable With Magnets
Magnets can be used to route and receive cables routed through walls. (magnet m image by Vita Vanaga from

Fishing wires through walls can be a challenging task, especially when it comes to retrieving the wires. A common scenario would be pulling new coaxial cable wires through a wall to hook up a flat-panel TV. Holding a magnet to attract the wire in the wall makes the extraction and inwall guiding process faster. All that is required is a magnet and ferrous object to make installation less of a headache.

  1. 1

    Tie string to a steel or iron nut. Loop the string two or three times around the wire, then secure it with a few wraps of electrical tape.

  2. 2

    Place the magnet on the end of fibreglass fish tape. Wrap two or three loops of electrical tape over the pairing to keep the magnet in place.

  3. 3

    Drop the cable, string and attached nut into the wall from the upper cutout or drilling point in the wall.

  4. 4

    Extend the fish tape up the wall through a cutout made directly below the first at the base of the wall, or where the wall plate will be located. You will feel the magnet engage the nut after the nut is attracted to it.

  5. 5

    Slowly pull the pairing through the wall. Grab the wire by hand and pull it out the rest of the way as needed. Remove the electrical tape, disengaging the string and fish tape.
