Homework Statement
A 2.6T magnetic field makes a 30 degree angle with a square loop 26cm on a side.
Homework Equations
phi=BAcos(theta)
The Attempt at a Solution
this should be a very simple question.
phi=2.6*.26^2cos30
phi=0.15Wb
mastering physics says this is wrong but I can't see any reason why? should it be negative or something?
thanks for any help/
