Compute the average induced emf in the secondary coil

Reference no: EM13294697

A very long, straight solenoid with a cross-sectional area of 6.15 is wound with 30 turns of wire per centimeter, and the windings carry a current of 0.235 . A secondary winding of 2 turns encircles the solenoid at its center. When the primary circuit is opened, the magnetic field of the solenoid becomes zero in 4.75×10?2 .

A) What is the average induced emf in the secondary coil?
