# A wire carrying a 31.0 A current bends through a right angle.

Exercise 28.13 - Enhanced - with Solution

A wire carrying a 31.0 A current bends through a right angle. Consider two 2.00 mm segments of wire, each 3.00 cm from the bend (Figure 1). Part A

Find the magnitude of the magnetic field these two segments produce at point P, which is midway between them. Express your answer with the appropriate units.

Part B

Find the direction of the magnetic field at point P.
