A solenoid 26 cm long has 2800 turns of wire and carries a current of 5.9 A. A 1500 turn coil of wire of the same length as the solenoid surrounds it and is concentric (shares a common central axis) with it. The outer coil carries a current of 10 A in the same direction as that of the current in the solenoid. Find the magnetic field at the common center.
