In Figure a wire forms a closed circular loop, with radius R = 2.0m and resistance 4.0Ω. The circle is centered on a long straight wire; at time t = 0, the current in the long straight wire is 5.0 A rightward. Thereafter, the current changes according to i = 5.0 A - (2.0 A/s2) t2. (The straight wire is insulated; so there is no electrical contact between it and the wire of the loop.) What is the magnitude of the current induced in the loop at times t > 0?
