Question

(b) Why do two circular current loops of the same size and with the same current di- rection attract each other when one is placed on top of the other but repel each other when they are placed side by side on the same plane? What happens in these two situations if the directions of current are opposite in the two loop (c) What are the similarities and differences for the microscopic basis of paramag- netism versus the microscopic basis for orientational polarization in dielectric ma- terials? What are the similarities and differences for the microscopic basis of dia- magnetism with the microscopic basis for electronic polarization in dielectric ma- terials?
