Question #4 A. [1 point] Explain briefly the factors affectingthe magnitude of the induced emf in an electricity generatingstation. B. [4 Points] A rectangular coil of 10 turns withdimensions 10 ?? Ã— 8 ?? sides is held perpendicular to the uniformmagnetic field, with half the area of the loop in the field, asshown the following figure. The loop contains an ideal battery withemf E = 1.5 ?. The magnitude of the magnetic field varies with timeaccording to ? = âˆ’ 4?2 + 3? + 3.0 , with B in teslas and t inseconds. (a)Calculatethemagnitudeanddirectionoftheemfinducedaroundtheloopat?=15???.(b) Find the net current with appropriate direction in the loop at? = 15 ??? if the loop has a resistance of 2 ohm
