A long solenoid has 1500 turns. When a current of 3.5 ~A flows through it, the magnetic flux linked with each turn of solenoid is 2.8 10⁻³ weber. The self-inductance of solenoid is
Options
- A1.2 H
- B2.4 H
- C3.6 H
- D6 H
Correct answer
A. 1.2 H
Step-by-step solution
Flux linked with each turn of the solenoid is, =2.8 10⁻³ ~Wb Total magnetic flux of the solenoid is, aligned & _ net = N & _ net =1500 2.8 10⁻³=4.2 ~Wb aligned Flux can also be given by, = LI The self-inductance of the solenoid is, aligned & L = I = 4.2 3.5 & ~L =1.2 H aligned
