Answer
(a) zero
(b) zero
(c) no
Work Step by Step
(a) We know that the magnetic field is parallel to the plane of the loop and hence the induced emf is zero.
(b) Although the current is increasing, the magnetic field is still parallel to the plane of the loop and that is why the induced emf is zero.
(c) As the magnetic field is still parallel to the plane of the loop, the answer to part (b) does not change.
