a very long, straight solenoid witha cross-sectional area of 6.25cm^2 is would with 44 turns of wire per centimeter, and the windings carry a current of .225A. 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 5.00*10^-2s
Part A What is the average inducted emf in the secondary coil?
