A solenoid of length 20cm, area of cross- section `4.0 cm^2` and having 4000 turns is placed inside another solenoid of 2000 turns having a cross - sectional area `8.0cm ^2` and length `10 cm`. Find the mutual inductance between the solenoids.

Text Solution

AI Generated Solution

To find the mutual inductance between two solenoids, we can follow these steps: ### Step 1: Identify the parameters of the solenoids - Inner solenoid (S1): - Length (l1) = 20 cm = 0.2 m - Cross-sectional area (A1) = 4.0 cm² = 4.0 × 10⁻⁴ m² - Number of turns (N1) = 4000 turns ...
