Explanation / Answer

Here ,

length of solenoid , L = 1.60 m

number of turns , N = 3200

current in the wire , I = 4 *10^-6 A

magnetic field inside a solenoid = u0*N*I/L

magnetic field inside a solenoid = 4pi*10^-7 * 3200 * 4 *10^-6/1.60

magnetic field inside a solenoid = 1.01 *10^-8 T

the magnetic field inside a solenoid is 1.01 *10^-8 T

the magnetic field outside solenoid is
