1. A method of manufacturing an electromagnet coil for use in a magnetic resonance imaging (MRI) system, the method comprising:
(a) computing a peripheral nerve stimulation (PNS) oracle penalty using a computer system, the PNS oracle penalty comprising a parameter representative of a PNS requirement for the electromagnetic coil;
(b) setting a plurality of performance metric requirements for a plurality of performance metrics for the electromagnet coil using the computer system;
(c) forming, by the computer system, a performance functional for generating a current density pattern over a coil surface for the electromagnetic coil, wherein the performance functional is based on the plurality of performance metrics and the PNS oracle penalty;
(d) optimizing, by the computer system, the performance functional based on the PNS requirement and the plurality of performance metric requirements;
(e) generating, by the computer system, a current density pattern over the coil surface based on the optimized performance functional; and
(f) outputting, to a display, information indicating the coil windings from the current density pattern.
