A long solenoid that has 1 080 turns uniformly distributed over a length of 0.420 m produces a magnetic field of magnitude 1.00 10-4 T at its center. What current is required in the windings for that to occur?

Current, I = 0.073 A

Explanation:

It is given that,

Number of turns in a long solenoid is 1080

Length of the solenoid is 0.420 m

It produces a magnetic field of at its center.

We need to find the current is required in the winding for that to occur. The magnetic field at the center of the solenoid is given by :

I is current

are there answer choices to this question? this seems like a question where you have options to choose from.

i think the answer would be b
