Two short bar magnets of magnetic moments  0.125Am2 and  0.512Am2  are placed with their like poles facing each other. If the distance between the centres of the magnet is 0.26m , the distance of neutral point from the weaker bar magnet is --------------

Let say the Null point distance from the weaker pole is x                                              To find null point, Baxial of both magnets should cancel out each other.∴μo4π2M1(x)3=μo4π2M2(0.26-x)3Now put, M1=0.125Am2M2=0.512Am2 ⇒0.125(x)3=0.512(0.26-x)3 ⇒5x=80.26-x ⇒x=0.1 m
