Question:
A square loop of wire (edge length 45 cm) is found to have an induced emf of 1.2 V at t 0.
(a) Assuming the magnetic field is perpendicular to the loop and that the magnitude of the field varies linearly with time, what is the change in the magnetic field from t = 0 to t = 0.10 s?
(b) Explain why it is only possible to compute the change in B and not its absolute magnitude.
