1. What is the average Magnetic Flux through one single coil at
the initial position of the bar magnet using 
initial = 2.32 x 10-3 T and 
= 2.292 x 10-4 m2.
2. What is the total average Magnetic Flux through all 1600
turns in the coil at the initial position of the bar magnet? This
is the value for 
initial.
3a. What is the average Magnetic Flux through one single coil?
b. What is the total average Magnetic Flux through all 1600
turns in the coil at the final position of the bar magnet? This is
the value for
final and it should be x 10-3 of
the
initial
value.
