Question about computing torque?

Question about computing torque??

When computing torque of a electic motor I use the formula T=IAB, where as I represents the current, A represents the area, and B represents the magnetic field. My question is, what is the meaning of the product of IA???

IA is the magnetic diapole moment of a current carring loop where I is the current and A is the area of the loop.
