What is the magnitude B of the magnetic field in the interior of the solenoid when the current in the solenoid is 3.00 A?

When the current in a long, straight, air-filled
solenoid is changing at the rate of 1500 A/s, the
voltage across the solenoid is 0.600 V. The
solenoid has 1200 turns and uniform cross-
sectional area 25.0 mm². Assume that the
magnetic field is uniform inside the solenoid and
zero outside, so the inductance formula
L = po AN? /l for a solenoid with N turns,
uniform cross-sectional area A, and length l,
applies.
