Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I don't know if you will find this question silly or not because I know it shouldn't be that hard but for some reason I keep getting it wrong. Here it is:

A square copper loop, with sides of length 10.4 cm, is located in a region of changing magnetic field. The direction of the magnetic field makes an angle of 34.0 degrees with the plane of the loop. The time-changing (increasing) field has the following time dependence: B(t)=0.600 T+(3.30×10-3 T/s)t.

Find the magnitude of the induced emf in the copper loop for times t>0.

Alright, so I was thinking this should be an easy faraday's law problem and I tried faraday's law: E = - d (flux)/dt = (B)(A)(cos(theta))*dB/dt

so I did: E = .6 * .104^2 * cos(34) * 3.3*10^-3 and I got 1.775 * 10^-5, which is wrong. The correct answer is 2.00 * 10^-5. Any ideas to what I did wrong?

Thanks
