Physics - Magnetism Question with Solution | TestHub

The coil carrying a current$\mathrm{i}$in clockwise sense coil has south polarity on that face of coil and other coil having current${\mathrm{i}}_2$in counter clockwise sense has north polarity on that face of the coil. As south and north poles will attract each other, hence a steady attractive force acts between the two coils.
