Ok i first misread this and assued that it meant parallel or sin(90 degrees) which equals 0.

I have thus far...

A = PI * r^2 = PI * .5^2 = .785 now plug thast into this formula.

t = NIAB = (?)(2)(.785)(.3). I know that to get the number of turns is number of loops divided by length. But there is no such animal, I have a feeling that I am using the wrong formula perhaps or have done something incorrect. Ive tripled check and still get .471 as my answer. What am I doing wrong?
