Interactive LearningWare 22.2 reviews the fundamental approachin problems such as this. A constant magnetic field passes througha single rectangular loop whose dimensions are 0.29 m x 0.61 m. Themagnetic field has a magnitude of 1.7 T and is inclined at an angleof 72o with respect to the normal to the plane of the loop. (a) Ifthe magnetic field decreases to zero in a time of 0.61 s, what isthe magnitude of the average emf induced in the loop? (b) If themagnetic field remains constant at its initial value of 1.7 T, whatis the magnitude of the rate A/ t at which the area should changeso that the average emf has the same magnitude?
