A wire loop of radius 0.165 m lies so that an external magnetic field of strength +0.24 T is perpendicular to the loop. The field changes to −0.32 T in 0.759 s.
Note: The plus and minus signs here refer to opposite directions through the coil.
Find the magnitude of the average induced emf in the coil during this time.
Answer in units of mV.
I thought I needed the number of loops to answer this, but radius is given instead. What equation(s) do I use?

Okay, so I just realized that the number of loops is only one, so I can still use the equation I was thinking of. Sorry about that!
