ABSTRACT:
A magnetic wire pulling system advances wire through a house or other structure around obstacles with a string tied to a pulling cord then tied to the wire. The system has small, medium, and large magnets, and tools attracted to the magnets. The round small and medium magnets are tied upon strings wound upon spools. The spools have pins to secure magnets. The tools comprise a retrieval tool, a manual release tool, an insertion tool, an automatic release tool, a transfer tool, an extensible prop, and a telescoping pole with magnet. The tools deliver a magnet into the structure of a house, retrieve a magnet from the structure, or transfer a magnet from one tool to another tool. In operation, a bigger magnet attracts a smaller magnet or a magnet attracts a tool to advance a string beyond an obstacle to continue pulling wire.
