Two co-axial identical circular current carrying loops are shown in figure, currents in them are in the same directions. Now, match the following two columns. {:(,"Column I",,"Colums II"),(A.,"Current i"_(1)" is increased",p.,"Loops will attract each other"),(B.,"Current i"_(2)" is decreased",q.,"Loops will repel each other"),(C.,"Loop-1 is moved towards loop-2",r.,"Current i"_(1)" will increase"),(D.,"Loop-2 is moved away from loop-1",s.,"Current i"_(2)" will increase"):}

Answer»


Solution :When current `i_(2)` is decreased, then flux through A decreases. According to LENZ's law, ATTRACTION occurs between A and B. SIMILARLY, when current `i_(1)` is increased, then loops will repel each other. As distance between the loop decreases, M decreases. Hence, loops will repel each other and current `i_(1)` will INCREASE, when loop 1 is moved towards loop 2. When loop 2 is moved away, loops will attract and `i_(2)` will increase.
