When the current in a toroidal solenoid is changing at a rate of 0.0240 A/s , the magnitude of the induced emf is 12.4 mV . When the current equals 1.50 A , the average flux through each turn of the solenoid is 0.00338 Wb. How many turns does soleniod has?

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.
