A magnet when placed perpendicular to a uniform field of strength \[{{10}^{-4}}Wb/{{m}^{2}}\] experiences a maximum couple of moment\[4\times {{10}^{-5}}N/m.\]. What is its magnetic moment [Bihar MEE 1995]

• A.            \[0.4A\times {{m}^{2}}\]
• B.            \[0.2A\times {{m}^{2}}\]
• C.            \[0.16A\times {{m}^{2}}\]      
• D.            \[0.04A\times {{m}^{2}}\] (e)     \[0.06A\times {{m}^{2}}\]
