2. -1 points My Notes A flat loop of wire consisting of a single turn of cross-sectional area 8.20 cm2 is perpendicular to a magnetic field that increases uniformly in magnitude from 0.500 T to 3.50 T in 1.03 s. What is the resulting induced current if the loop has a resistance of 1.40 S? mA Submit Answer Save Progress Practice Another Version 3. t -1 points My Notes A strong electromagnet produces a uniform magnetic field of 1.60 T and a cross-sectional area of 0.200 m2, If we place a coil having 190 turns and a total resistance of 16.0 around the electromagnet and then we then smoothly reduced the current in the electromagnet t reaches zero 20.0 ms, what is the current induced in the coil until 4, -1 points My Notes Consider the arrangement shown in Figure P31.20. Assume that R 6.00 S, t 1.20 m, and a uniform 1.50 T magnetic field is directed into the page. At what speed should the bar be moved to produce a current of 0.500 A in the resistor? m/s
