A smal, dosely wound coil has N tuns, area A, and resistance R. The col is intaly in a uniform magnetic feld hat has magnitude B and a drecton perpendicular to the plane of the loop The collis then rapidly pulled out of the Teld so that the fux through the colis reduced to zero in time • Part A What are the magnitude of the average emf E and average curent I, induced in the col? Express your answer in terms of the variables N, A, R. B, and At. AZ ? • Part B The oalchage O hat fous thrugh he coli gven by Q = IAt. Derive an expresson frQ in ems of N, A,B. and R Note that Q d not depend on At. Express your answer in terms of the variables N, A, R, and B. ?
