Answer:
The number of turns in the solenoid is 230.
Explanation:
Given that,
Rate of change of current,
Induced emf,
Current, I = 1.5 A
Magnetic flux,
The induced emf through the solenoid is given by :
or
........(1)
The self inductance of the solenoid is given by :
.........(2)
From equation (1) and (2) we get :
N is the number of turns in the solenoid
N = 229.28 turns
or
N = 230 turns
So, the number of turns in the solenoid is 230. Hence, this is the required solution.
