A long solenoid that has 1130 turns uniformly distributed ov

A long solenoid that has 1,130 turns uniformly distributed over a length of 0.385 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?

____ mA

(Please show work and answer so I can compare)

Solution

B = 0 x N/L x I
B = 1.00 x 10-4 T
0 = 1.26 x 10-6

N/L =1130/0.385 = 2935.065

1.00 x 10-4 T = 1.26 x 10-6 x 2935.065 x I

10^-4 =0.003698 x I

I = 27.0416 mA
