Question Details:
A coil of 16 turns and radius 10.0 cm surrounds a long solenoid of radius 2.20 cm and 1.00 103 turns/meter. The current in the solenoid changes as I = (8.00 A) sin(100 t). Find the induced emf in the 16-turn coil as a function of time t. (For this question only, assume that all trailing zeros are significant, and provide exactly 3 significant figures for all numbers included in your expression below.)

I went thru the calculation and obtained .0245 cos 100t
The minus sign is probably not needed and an additional significant figure is apparently needed.
