Two short magnets of magnetic moment  1000Am2 are placed as shown at the corners of  a square of side  10cm the net magnetic indication at  P  is

For Bar Magnet 1 , P is equatorial point : B1=Be=μ04πMd3=10-7×1000(0.1)3=0.1TFor Bar Magnet 2 , P is axial point :B2=Ba=μ04π2Md3=10-7×2×1000(0.1)3=0.2T∴Bnet =B2-B1=0.2-0.1=0.1T
