In which direction would the magnetic field on the axis at a distance $Z$ from the centre of the bar magnet be?

  • A
    In the direction of the magnetic dipole moment ( $\overrightarrow{M}$ ) of the magnet.
  • B
    In the opposite direction of the magnetic dipole moment ( $\overrightarrow{M}$ ) of the magnet.
  • C
    In the perpendicular direction of the magnetic moment ( $\overrightarrow{M}$ ) of the magnet.
  • D
    Its direction depends on the magnitude of the magnetic moment ( $\overrightarrow{M}$ ) of the magnet.
