Consider the following figure. (a) A conducting loop in the shape of a square of edge length f = 0.420 m carries a current I = 9.20 A as in the figure above. Calculate the magnitude and direction of the magnetic field at the center of the square. magnitude HT direction ---Select--- (b) 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? magnitude HT direction -Select
