The resistivity of silver is 1.59 x 10^-8
Part A: "As shown below, a wire loop (that is immersed in a 0.86 T B-field) shrinks from a radius of 52 cm to a radius of 2.9 cm in 0.52 s. The wire loop has a constant resistance of 0.16 Ω. Find the induced voltage & the induced current."
Part B: "As shown below, there are two concentric silver wire loops; a 5 cm radius loop and a 43 cm radius loop. The cross-sectional area of each wire is 0.006 m2. The current in the larger loop goes from a counterclockwise 5.8 A to 0 A in 9.7 x 10-4 s. Find the voltage & current in the smaller loop during the stated time interval. Assume the B-field of the larger loop is uniform (though not constant) across the smaller loop."
