An infinitely long wire carrying a current of 3.30 A is bent at a right angle as shown in the figure.

An infinitely long wire carrying a current of 3.30 A is bent at a right angle as shown in the figure. Determine the magnitude and direction ( +k, -k, +j, -j, +i, -i) of the magnetic field at the point P a distance a = 21.5 cm from each leg of the right angle bend.
