### Statement
−$9.3.13.$ [Insert the problem statement]
+$9.3.13.$ A cylindrical ferromagnetic column with narrow cavities was placed in a long solenoid with a current of
+$0.5 A$. The number of turns per $1 cm$ of the length of the solenoid is $10$, the magnetic permeability of the
+ferromagnet is $600$. Determine the magnetic field induction in the longitudinal and transverse cavities
+(at points $A$ and $B$).
### Solution
−Внутри продольного разреза поле соответствует полю соленоида, внутри поперечного усиливается в соответствии с магнитной проницаемостью:
−$$B_{||}=\mu_0 I n \approx 6,28 \cdot 10^{-4} Тл$$
−$$B_{\perp}=\mu \mu_0 I n \approx 0,377 Тл$$
+Inside the longitudinal section, the field corresponds to the field of the solenoid, inside the transverse section it is amplified in accordance with the magnetic permeability:
+$$B_{||}=\mu_0 I n \approx 6,28 \cdot 10^{-4} Т$$
+$$B_{\perp}=\mu \mu_0 I n \approx 0,377 Т$$
+
#### Answer
−[Insert a concise answer or boxed result]
+$$B_{||}=\mu_0 I n \approx 6,28 \cdot 10^{-4} Т$$
+$$B_{\perp}=\mu \mu_0 I n \approx 0,377 Т$$
