A current of 7.79 A in a solenoid of length 10.6 cm creates a 0.201 T magnetic field at the center of the solenoid. How many turns does this solenoid contain? turns :

Therefore,

2178 number of turns are there in Solenoid.

Explanation:

Given:

Current, I = 7.79 A

Length of Solenoid,

magnetic field at the center of the solenoid,

B = 0.201 Tesla

To Find:

N = ? turns

Solution:

Magnetic field at the center of the solenoid is given as,

Where,

B = Magnetic Field,

N = Number of turns,

I = Current,

L = Length of Solenoid

Substituting the values we get

Therefore,

2178 number of turns are there in Solenoid.

i need the answer to this too but idk it ; -;
