An air-core solenoid contains 1060 m
of wire per meter and has a cross-sectional
area of 0.23 m. A current of 5.57 A is es-
tablished in the solenoid and is then reduced
linearly to zero in 5.24 s. A pickup coil of 50
turns circles the solenoid near its center.
What is the magnitude of the induced emf
in the pickup coil?
Answer in units of V.
