If we have a loop with radius 12 cm that lies in a uniform magnetic field of 1.5T.(adsbygoogle = window.adsbygoogle || []).push({});

The magnetic field is in the positive z direction and the loop lies in the horizontal xy-plane. Now if the loop is removed from the field in a time interval of 2.0x10^-3 s what will the average induced emf be.

Right now first I thaught it might be zero but then seeing as the b field will be constant and A will change.

therefore it has to be emf= - -b x dA/dt

but how can i describe the rate of change of A?

ps:am I even on the right track? =)
