Grade 12Magnetism

Sir , in magnetism we study about
Vector T= vector M cross vectorB, for moment of couple in uniform magnetic field for current carrying loop.
Where T = moment of couple.
M=magnetic dipole moment.
B=magnetic field.
So, can you please tell me what is the significance of T when we use our right hand rule for finding T through M cross B.........

T is actually the torque experienced by the loop. 
 
Its formula is M*B
                         MBsinΦ
    It means that the direction of T will be perpendicular to the plane where both M and B are lying.
