Homework Statement
I have to calculate the induced current in a coil a known distance from a solenoid (the secondary coil is on the axis of the solenoid). As the magnetic flux from the solenoid weakens with distance, I have applied biort-savart law to determine the stength of the magnetic field at a point from the solenoid. My question is, when I am calculating the induced current in the second coil, do I do so by considering the magnetic field stength at the center of the second coil, or do I find an average field strength by considering the field strength at all the points along the axis of the coil?

The Attempt at a Solution
I think that it's more appropriate to consider the average field strength throughout the second coil, but I am not sure. Can anyone help me please?
