What is the magnetic field induction (of earth) when a bar magnet is placed with its axial line   perpendicular to magnetic meridian with North pole facing towards east to achieve neutral point?

In this case two null points are obtained one N1  is in  (N-W  direction ) and another  N2(S-E  direction)We know  magnetic field induction at any point isBH=μ04πMd31+3cos2θHere   tanθ=2∵cosθ=13 BH=μ04π2Md3  Hence key (2) is Correct & Remaining (1),(2),(4) are not correct
