Two very long concentric solenoids, having radii r < r2 are placed inside one another, as shown. Both solenoids carry a current of 5.7 A but circulating in opposite directions. When the current is running in both solenoids, the magnetic field inside the smaller solenoid is 0.26 mT. If the number of turns per length N/L for the smaller one is 370 turns/m. What is the number of turns per length for the larger solenoid? Side View Head-on View T2
