The smaller loop (radius r) is above the larger loop (radius R), by distance x>>R. The magnetic field due to current i in the larger loop is nearly constant throughout the smaller loop. Suppose that x is increasing at a constant rate of dx / dt =v. find The induced emf in the smaller loop is

A wire loop with a = 10 cm and b= 15 cm and a long straight wire is arranged as shown in fig. the current in the wiire is changing according with a relation i = 5 t^2 - 10 t Figure shows two parallel and coaxial loops. The smaller loop (radius r) is above the larger loop (radius R) where I is in amperes and t is in seconds a) find the emf in the square loop t = 4 s? b) what is the direction of the induced current in the loop ?
