PROBLEM DEFINITION:

Need statement:

Wire winded coils are used in motors,solenoids,inductors and many other electrical equipments. Today,coil windings are no more preferred by labors. Industrial machines are much efficient and fast in doing this job.An industry which manufactures such machines is interested in making ready a small scale demo machine.
