Homework Statement
A flat, square surface with side length 3.00cm is in the xy-plane at z=0 .
Calculate the magnitude of the flux through this surface produced by a magnetic field
B=(0.150T)i+(0.350T)j-(0.500T)k
What I'am doing is I know that the magnetic flux= BAcos(theta)
So I multiply my vector B by 0.03m and get (0.0045)i+(0.0105)j, and z=0 so I can ignore that value.
Then they are asking for the magnitude, so √(0.0045)^2+(0.00105)^2= 0.00462Wb , however that is not giving me the correct answer, what am I missing?
Thanks
