Homework Help: Physics

Posted by Valerie on Sunday, April 7, 2013 at 8:30pm.

A single-turn square loop of side L is centered on the axis of a long solenoid. In addition, the plane of the square loop is perpendicular to the axis of the solenoid. The solenoid has 1490 turns per meter and a diameter of 6.00 cm, and carries a current of 2.46 A. Find the magnetic flux through the loop in each of the following.
a) L = 3cm
b) L = 6cm
c) L = 12cm

I found a to be 4.15e-6, b to be 1.66e-5 and c to be 6.63e-5, but only a is right. the answers are within ten percent of 1.2e-5 and are the same answer but I can't find what they should be. Please someone help soon.
