Two solenoids made of insulated conducting wires and of equal lengths are such that one is wound over another. Resistance of each of them is R and number of turns per unit lenghts is n. The solenoids are now connected in parallel and the combination is then connected with a battery of emf E. if current flows through them in the same direction in both cases, determine the magnetic field along the axis of solenoids in each case.

Two solenoids made of insulated conducting wires and of equal lengths are such that one is wound over another. Resistance of each of them is R and number of turns per unit lenghts is n. The solenoids are now conected in series and if current flows through them in the same direction in both cases, determine the magnetic field along the axis of solenoids in each case.
