The diagram below shows a long wire with a right angle bend. A current of I = 2.88 A flows through the wire. Determine the magnetic field (in unit vector notation) at the point P which is a distance a = 2.10 cm from the corner of the bend. (Assume that the +x axis is directed to the right, the +y axis is directed up, and the +z axis is toward you.)
