Questions
A wire is bent to form the double loop shown in figure. There is a uniform magnetic field directed into the plane of the loop. If the magnitude of this field is decreasing, the current will flow from
detailed solution
Correct option is C
By Lenz's law, clockwise current is induced in both loops. Greater the area, larger will be the induced emf. Since, outer loop has greater area, current will flow according to emf induced in outer loop i.e. a to b to d to c to a.Talk to our academic expert!
