    If a bar magnet of length land cross-sectional area A is cut into two equal parts as shown in figure, then the pole strength of each pole becomes

    Pole strength depends on material of magnet, state of magnetization and cross-sectional area. As m proportional to A comma so if Abecomes half, pole strength gets half.
