Vedclass · Answer

(A) Magnetic field lines are continuous closed loops. Outside the magnet,they emerge from the North pole $(N)$ and enter the South pole $(S)$. Inside the magnet,they travel from the South pole $(S)$ to the North pole $(N)$. This ensures that the lines of magnetic induction form continuous paths. Looking at the provided figures,figure $(1)$ correctly depicts these lines emerging from the North pole,entering the South pole,and continuing through the interior of the magnet from $S$ to $N$.

In the following figures,the lines of magnetic induction due to a magnet $SN$ are given by:
