Question
Describe experiment of two coils explaining electromagnetic induction.
✓
Answer
→As shown in figure, two coils $C _1$ and $C _2$ are kept facing each other.
→Galvanometer is connected with $C _1$ and Battery is connected with $C _2$.
→On passing steady current through coil $C _2$, magnetic field is produced around it.
→On moving $C _2$ towards $C _1$, galvanometer shows deflection. It indicates that electric current is induced in $C _1$.
→On moving $C _2$ away from $C _1$, galvanometer shows deflection in opposite direction.
→Keeping $C _2$ stationary, on moving $C _1$ closer to or away from $C _2$, we get same results as above.
→Thus, here electric current is induced due to relative motion between both coils.
