1.	A planar loop of irregular shape encloses an area of `7*5xx10^-4m^2`, and carries a current of `12A`. The sense of flow of current appears to be clockwise to an observer. What is the magnitude and direction of the magnetic moment vector associated with the current loop?
Answer» Here, `A=75xx10^-4m^2, I=12A` As `M=IA` `:. M=12xx75xx10^-4=9xx10^-3Am^2` The direction of `vecM` is perpendicular to the plane of the loop and away from the observer (according to Right hand palm rule).
