magnetic effect of current and moving charges

Description Image

Evaluate magnitude and direction of magnetic field at a point P .

the magnetic field due to each side will be same in magnitude and direction. so take any one side. find out the angle made by the side at the centre. then find the perpendicular distance from the side to point P. Finally use biot savart law.

Ignore my previous comment. The diagram shows different directions of current.the magnitude is same for each side. find the directions using thumb rule. for finding the magnitude take one side and calculate the angle made by the two end points of sides at the point P. use biot savart law to find the magnitude.
