1. A system for generating an electromagnetic field, comprising:
- a jig comprisinga center member, anda plurality of coil-separating blocks protruding from the center member and are separated from each other to provide a plurality of coil channels; and
a plurality of wires, wherein each of the plurality of wires is wrapped on the jig, around the center member, and in one of the plurality of coil channels to form one of a plurality of coils, wherein each of the plurality of coils is configured to operate with an electromagnetic navigation system and generate respective electromagnetic fields to be emitted relative to a subject;
wherein;
the plurality of coil channels comprise dividers and wire channels; and
each of the plurality of wires are wrappedin one of the wire channels,around the center member, andbetween two of the dividers or between one of the dividers and one of the coil-separating blocks;
wherein;
the plurality of coil channels are segregated with gaps between segregated portions of the plurality of coil channels, wherein a first coil channel is segregated by a second coil channel such that gaps of the first coil channel are in the second coil channel; and
each of the plurality of wires switch between wire channels in the gaps of the segregated portions of the plurality of coil channels.

Abstract
An electromagnetic device includes a jig and multiple wires. The jig includes a center member and coil-separating blocks. The coil-separating blocks protrude from the center member and are separated from each other to provide a coil channels. Each of the wires is wrapped on the jig, around the center member, and in one of the coil channels to form one of a multiple coils. Each of the coils is configured to connect to an electromagnetic navigation system and generate respective electromagnetic fields to be emitted relative to a subject.
