Explain with the help of a labelled diagram the distribution of magnetic field due to a current through a circular loop. If a current carrying coil has n turns, why is the field produced at any point n times the field produced by a single turn ?

1.	Explain with the help of a labelled diagram the distribution of magnetic field due to a current through a circular loop. If a current carrying coil has n turns, why is the field produced at any point n times the field produced by a single turn ?
Answer» Solution :A CIRCULAR LOOP formed by bending a straight conductormay be imagined as many small pieces of straight wires. Eachof thesepieces produces a magnetic field in theform of concentric circles of increasing radius centred aroundthe WIRE. At the CENTRE of thecircular loop, the arcs of these bigcircles would appearas straight LINES. The right-hand thumb rule shows that every section of the wire contributesto themagnetic fieldlines in the same direction withinthe loop.
