Question 139 of 153
This question has Statement 1 and Statement 2. Of the four choices given after the Statements, choose the one that best describes the two Statements.
Statement 1: Self inductance of a long solenoid of length , total number of turns and radius is less than .
Statement 2: The magnetic induction in the solenoid in Statement 1 carrying current is in the middle of the solenoid but becomes less as we move towards its ends.
Show answer and solution
Answer: (B) Statement 1 is true, Statement 2 is true, Statement 2 is the correct explanation of Statement 1.
Self inductance of a long solenoid is given by
Magnetic field at the centre of solenoid
So both the statements are correct and statement 2 is correct explanation of statement 1
Magnetic field at the centre of solenoid
So both the statements are correct and statement 2 is correct explanation of statement 1
