When a straight conductor is taken into consideration, the flow of direction of force is placed at tangential format in a circular line. As per the work law that is used for determining the actual condition of operating of this process, when a North Pole situation is considered, the singular path that is completed is equivalent to ampere that is covered in this path.

When an electric conductor is moved a flow of electric charges could be induced into that resulting in framing of a wire that has electric charges placed in a magnetic field.

Work = Force x Joules

Further sums by students can be doneonly when these concepts are understood by them in a better manner.
