Two identical small bar magnets, each having magnetic dipole moment 3√5 J·T⁻¹, are placed with their axes perpendicular to each other as shown in the figure. Their centre-to-centre separation is 10 cm, and point P is midway between them. Taking μ₀ = 4π×10⁻⁷ T·m·A⁻¹, if the net magnetic field at P is α×10⁻³ T, find α.
