When running. the solenoid produced a field of 1.5 T in the center Given this, how large a current does it carry? Express your answer using two significant figures. kA Submit My Answers Give Up Continue 4:30 PM 10/26/2017

Explanation / Answer

Here,

let the current is I

for the solenoid

B = u0 * N * I/L

1.5 = 4pi *10^-7 * 1100 * I/1.9

solving for I

I = 2062 A

I = 2.06 kA

the current is carries is 2.06 kA
