A 275 turn solenoid with a length of 27cm and a radius of 1.1cm carries a current of 2.3A. A second coil of 4 turns is wrapped tightly about this solenoid so that is can be considered to have the same radius as the solenoid. (a)Find change in the magnetic flux through the coil when the current in the solenoid increases to 5.9A in a period of 0.93s. Answer in units of Tm^2. (b)Find the magnitude of the average induced emf in the coil, answer in units of uV.
