Q5:
(a) A conducting loop in the shape of a square of edge length ,l =m carries a current I = A as shown in Figure P30.5. Calculate the magnitude and direction of the magnetic field at the center of the square.
(b) What If? If this conductor is reshaped to form a circular loop and carries the same current, what is the value of the magnetic field at the center?
