This is from electromagnetic induction ncert Please give a detailed solution of d part Why will polarity of A be pos tive Will the poles be induced in this coil Both are comi ng towards it I m not able to judge the increase or decreas e in magnetic flux and hence direction of current Please e plain the concept behind this question UKE 0 0 AMPLE 6 5 d Predict the polarity of the capacitor in the situation described by Fig 6 9 S A B FIGURE 6 9 2021 S Solution a No However strong the magnet may be current can be induced only by changing the magnetic flux through the loop b No current is induced in either case Current can not be induced by changing the electric flux c The induced emf is expected to be constant only in the case of the rectangular loop In the case of circular loop the rate of change of area of the loop during its passage out of the field region is not constant hence induced emf will vary accordingl
