Homework Statement
A horizontal desk surface measures 4.3 m by 2.0 m. If the Earth's magnetic field has magnitude 0.32 mT and is directed 45° below the horizontal, what is the magnetic flux through the desk surface?
Homework Equations
Flux = B*A*Cos(a)
Where A is the area, B is the magnetic field,
The Attempt at a Solution
Flux = B*A*Cos(a)
= (.32E-3 T) * (4.3*2.0 m^2) * ( Cos(45) )
= 0.00194596 T*m
However, the my solution isn't correct and I'm convinced that I'm not doing anything incorrectly.
