The change in the magnetic flux during the coil

Reference no: EM13660219

A 500 turn solenoid by a length of 20 cm and a radius of 1.5 cm carries a current of 2.0 A. A second coil of four turns is wrapped tightly about this solenoid so that it can be considered to have the similar radius as the solenoid. Find the following when the current in the solenoid increases to 5.0 A in a period of 0.90 s.

a) The change in the magnetic flux during the coil

b) the magnitude of the average induced emf in the coil
