A small, closely wound coil has /V turns, area A, and resistance R. The coil is initially in a uniform magnetic field that has magnitude B and a direction perpendicular to the plane of the loop. The coil is then rapidly pulled out of the field so that the flux through the coil is reduced to zero in time At. Part A What are the magnitude of the average emf &av and average current lav induced in the coil? Express your answer in terms of the variables IV, A, R, B, and At. AED ? Eav, Jav = Submit Request Answer Part B The total charge Q that flows through the coil is given by Q = lav At. Derive an expression for Q in terms of NV, A, B, and R. Note that Q does not depend on At. Express your answer in terms of the variables IV, A, R, and B. IVO ? Q = Submit Request Answer Part C What is Q if I = 150 turns, A = 4.50 cm, R = 30.0 0, and B = 0.200 T? Express your answer with the appropriate units. HA ? Q = Value UnitsA circular loop of wire with a radius of 15.0 cm and oriented in the horizontal xy-plane is located in a region of uniform magnetic field. A field of 1.3 T is directed along the positive z-direction, which is upward.
