Magnetic Field from Current Loop

A loop carries current I = 2.5 A in the x-y plane as shown in the figure above. The loop is made in the shape of a circular arc of radius R = 4 cm from θo = 60 ° to θ = 360 ° . The loop is completed by horizontal and vertical sections as shown.
What is BA, the magnitude of the magnetic field at point A, the center of the circular arc?

BA = T
