Vedclass · Answer

(B) When a magnet is cut along its length,the pole strength remains the same,but when it is cut perpendicular to its length,the pole strength is halved.In this case,the magnet is cut into four equal parts by cutting it once along its length (parallel to the axis) and once perpendicular to its length.$1$. Cutting along the length (parallel to the axis) divides the pole strength $m$ into $m/2$ and $m/2$.$2$. Cutting perpendicular to the length divides the magnet into two parts,but the pole strength of each cross-section remains $m/2$.Therefore,for each of the four resulting parts,the pole strength $m^{\prime}$ is $m/2$.
