Find the magnetic flux through a solenoid of length 31.2 cm, radius 1.5 cm, and 610 turns that carries a current of 3.8 A.
Flux= B *A
The Attempt at a Solution
So to find the magnetic field, I plugged the values into the equation like this: u0*610*3.8/.312=9.34*10-3.
And I've tried doing pi*(.0152) for the area, and multiplying them together, and I didn't get the right answer.
I tried taking the total surface area of the solenoid, such as 2pi(.015)2* 2pi(.015)*(.312) and I still can't get the answer. What am i missing? I feel like this problem should be really easy...
