"get more wire"
the wire is going to be the same resistance as the resistance of the material of the wire.
if it is insulated then you can remove the insulation.
realy though you would need to get a more conductive wire. or often it works to increase the size of the wire if you have a "heat" generation issue.
Its the wires atomic structure.
you can use very high tech processes to align the atomic or even subatomic structures. you can also induce fields but really you arn't "changing the resistance " unless you change the energy transfer process.

Traditional methods to lower wire resistance effectively include:
(1) use a different alloy (plating the surface can work as well, but
this may not always give the results desired)
(2) use a larger wire diameter, or in some cases use stranded
wire
(3) chill the wire

1. Shorten the wire
2. Increase the diameter
3. Reduce the the temperature
4. Change the material the wire is made of (i.e. gold)

Increase the cross-sectional area or shorten the loop. Increasing the area is more effective.
R = ρL/A

1. increase the cross sectional area of the wire
2. try to reduce the length of the wire.

use a thinner and shorter wire

use silver wire
