a) Assume that there is a long ideal solenoid with 120 turns/cm.It carries a current i= 2 A and it has a diameter 2 cm and a length5 m. Find the uniform magnetic field inside the solenoid.
c) Now, construct an RL circuit using an ideal batterythat has potential difference 5 V, one resistor with R = 2 Ω andthe solenoid that has same shape with one mentioned at part (a).Wait very long time and then remove the battery. Find the potentialdifference across resistor at 2 ms after removing battery?(Hint: First calculate the inductance)
