Consider a system consisting of two long, concentric solenoids, as shown below in cross section. The current in the outer solenoid is 11 = 1.40 A, while the current in the inner solenoid is 12 = 2.23 A flowing in the opposite direction. The outer solenoid has 101 turns per centimeter, and the inner solenoid has 131 turns per centimeter. Find the magnetic field strength in the region between the two solenoids. Enter your answer as a positive number if the field points up Submit Answer Tries 0/16 Find the magnetic field strength inside the inner solenoid. Enter your answer as a positive number if the field points up

Explanation / Answer

outer solenoid n = 101/cm = 101 / 10-2 = 10100

for inner solenoid n = 131/cm = 13100

B= mu0 n i

= 4pi * 10-7* 10100 * 1.40

= 17.76 mT

--------------------------------------------------

b) Binner = 4pi * 10-7*13100 * 2.23 = 36.71 mT

B= Binner- Bouter

= 36.71 - 17.76 = 18.95 mT
