pletion Status: QUESTION 11 A single-turn circular loop of wire of radius 31.0 mm lies in a plane perpendicular to a spatially uniform magnetic field. During a 80.0 ms time interval, the magnitude of the field increases uniformly from 250 to 400 ml. Determine the emf in millivolts (mV) induced in the loop. 5 points Save Answer

Answer 1

3) Solution glven an Question N=1 (single torm) 8310mm = 0.031m and applied Magnetic held is I to the plane of the loop and Magnetic Kield change change from 250 to goomt in t=80.0ms = 0.08 sec - The Magnetic netic fluy passing through the loop is Om = BA = A AB (Because B is variable) g so induced emit an loop ·NADB -NDOM Z and DB = 400 - 250 = 150m T = 0.150 T or som is E = دن

and Area Equals (0.031)? A=08² = 0 So E=/- (0) «(160-031)) (0-15) 008 0.6056 u = Or E=5.6mv so emf induced in the loop is E = 5.6mu
