The self-inductance L of a solenoid of length and area of crosssection A with a fixed number of turns N increases as
Options
- Aincreases and A decreases
- Bdecreases and A increases
- Cboth and A increase
- Dboth and A decreases
Correct answer
B. decreases and A increases
Step-by-step solution
The self-inductance L of a solenoid of length b and area of cross section A with fixed number of turns N is L= ₀ N^2 A b So, L increases when b decreases and A increases
