A square loop of side a is located in a region of changing magnetic field. The direction of the magnetic field makes an angle of 6 degrees with the place of the loop and B(t) = b + ct in Tesla. Find the magnetic flux through the loop as a function of time (ignore the minus sign). a^2(b+ct)cos theta a^2ctcos theta a^ccostheta a(b+ct)cos theta abct)cos theta Find the induced emf in the copper loop for t > 0. a^2(b+ct)cos theta a^2ctcos theta a^2ccos theta a(b+ct)costheta abct)cos theta
