A very long solenoid with a circular cross section and radius r1= 1.30 cm with ns= 260 turns/cm lies inside a short coil of radi
allochka39001 [22]

Answer:

0.00851 volts

Explanation:

radius r1= 1.30 cm with ns= 260 turns/cm

radius r2= 4.60 cm and Nc= 23 turns

constant rate from zero to Is= 1.90 A

time interval of 88.0 ms

Area of the solenoid

A_1=\pi*r_1^2

=\pi*0.013^2

A_1=5.31*10^-^4 m^2

Mututal Inductance

M=uo*n*N*A1

M=(4\pi*10^-^7)*23*(260*10^2)*(5.31*10^-^4)

M=3.99*10^-^4 H

a)

EMF induced in the outer coil

E=M(dIs/dt)

E=(3.99*10^-^4)*(1.9/88*10^-^3)

E=0.00861 Volts
