The magnetic field B generated by this current is in the negative y- direction as shown.

Problem 2 A conducting loop in the shape of a square with areaA = 2m2 and resistance R = 109 is placed in the yz-plane as shown. A time—dependent magnetic field B = Bxi is applied. Its time dependence Bx(t) is shown graphically. y (a) Find the magnetic flux (Dm through the loop at time I: 0.
