Solenoid Question!?

1 ⤊

A solenoid is 15cm long and has 250 turns. What is the magnetic field strength inside the solenoid if the current in the coils is 3.8A?

Please show explanation and if it helps, the answer is 8.0 x10^-3 T

B = μ N I = μ (n / L) I

where μ = 4 pi E-7
N is the number of turns per meter
I is the current in amperes.

B = μ N I = 4 pi E-7 x (250/.15) x 3.8
B= 8.0 E -3 Tesla
