Transcribed Image Text:A circular loop in the plane of the page has a uniform magnetic field field passing through it.
The radius of the loop is r = 12 cm. At time t = 0 s the magnetic field has a magnitude of 10 mT and
points out of the page. A tenth of a second later (t = 0.1 s), the magnetic field has a magnitude of
5 mT and points into the page. What is the induced EMF in the loop (magnitude and direction).
(a) 1.2 mV counterclockwise
(b) 6.8 mV counterclockwise
(c) 1.2 mV clockwise
(d) 6.8 mV clockwise
