Hat is the magnetic field at given point

Reference no: EM13255099

Consider a long wire that makes a right angle (90°) bend. If the wire carries a current I, what is the magnetic field at point A? Hint: Use the result for the field from an infinitely long wire (Eq: B = U*I / 2 pi r) to find the field produced by a "semi"-infi nite wire (i.e., half of an infinite wire).
