Question

Figure shown plane figure made of a conductor located in a magnetic field along the inward normal to the plane of the figure. The magnetic field starts diminishing. Then the induced current           a)At point P is clockwiseb)At point Q is anticlockwisec)At point Q is clockwised)At point R is zeroCorrect answer is option 'A,C,D'. Can you explain this answer?

Answer

As the field diminishes the current is induced in the coils such that if opposes the diminishing of the field. Hence, current is induced in clockwise directing in both the loops.
And as the loops are closed no current will come out of the loops and no current at point R.
Hence option A C D is the correct option.

Answer

Use RHR(right hand rule)
