# Question

(a) A conducting loop in the shape of a square of edge length ℓ = 0.380 m carries a current I = 10.2 A as in the figure above. Calculate the magnitude and direction of the magnetic field at the center of the square.

(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?
