Question

3. A magnetic field directed out of the page changes with time
according to ? = (0.02?
2 + 0.6?)? where ? is in seconds. A circular
conducting wire of radius ? = 2.5?? and resistance of ? = 5Ω is placed in
that field region. (i) Calculate the induced emf in the circuit when ? = 2?.
(ii) Using the Lenz’s law, determine the direction and magnitude of induced
current. Explain your answer.
