Consider a system consisting of two long, concentric solenoids, as shown below in cross section. The current in the outer solenoid is $I_1$ = 2.00 A, while the current in the inner solenoid is $I_2$ = 2.92 A flowing in the opposite direction. The outer solenoid has 103 turns per centimeter, and the inner solenoid has 136 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. Find the magnetic field strength inside the inner solenoid. Enter your answer as a positive number if the field points up.

Consider a system consisting of two long, concentric solenoids, as shown below in cross section. The current in the outer solenoid is I = 2.00 A, while the current in the inner solenoid is I = -3.92 A flowing in the opposite direction. The outer solenoid has 105 turns per centimeter, and the inner solenoid has 128 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. Find the magnetic field strength inside the inner solenoid. Enter your answer as a positive number if the field points up.

Consider a system consisting of two concentric solenoids, as illustrated in FlGuRE $22-62 .$ The current in the outer solenoid is $I_{1}=1.25 \mathrm{A},$ and the current in the inner solenoid is $I_{2}=2.17 \mathrm{A}$ . Given that the number of turns per centimeter is 105 for the outer solenoid and 125 for the inner solenoid, find the magnitude and direction of the magnetic field (a) between the solenoids and (b) inside the inner solenoid.
A long solenoid with 60 turns of wire per centimeter carries a current of 0.15 A. The wire that makes up the solenoid is wrapped around a solid core of silicon steel ($K_m =$ 5200). (The wire of the solenoid is jacketed with an insulator so that none of the current flows into the core.) (a) For a point inside the core, find the magnitudes of (i) the magnetic field $\overrightarrow{B_0}$ due to the solenoid current; (ii) the magnetization $\overrightarrow{M}$; (iii) the total magnetic field $\overrightarrow{B}$. (b) In a sketch of the solenoid and core, show the directions of the vectors $\overrightarrow{B}$, $\overrightarrow{B_0}$, and $\overrightarrow{M}$ inside the core.
