A current I flows along an equilateral triangle of side length ''a'' . What is the magnitude and direction of magnetic field intensity at the centre of the loop ?? (Magnitude-wise is easy that what i got but how to get direction ??)

Utilizing the correct hand run the show. 
Make a thumbs up sign such that the thumb focuses towards the stream of current. 
In this circumstance the rest of the 4 fingers that are right now twisted speaks to the heading of the attractive field produced by the current conveying conductor. 
For an illustration, how about we consider there is a current conveying straight conductor and current is spilling out of South to North heading, so in the event that you make a thumbs up sign where current streams toward thumb, the attractive field is towards the top, out of the surface.
