Many applications of such polymers, such as for use as motor windings or as magnetic field sensors, require a precise knowledge of the electrical properties of the polymers being used. This thesis presents a study of the magnetoresistance of the conducting polymer polypyrrole. It was found that the electrical resistance of polypyrrole wires is not correlated to the strength of a perpendicular magnetic field, but exhibits a large dependence on the operating temperature of the wire.</dim:field>
