Answer 1

Answer:

yes because of changing magnetic field which are there due to increase in current

Answer 2

SoluTion :-

No, there will not be an induced emf occur in the loop as magnetic flux doesn't change linked with the circular loop because magnetic field lines are parallel to the plane of the loop.

$\sf {As\ Induced\ emf (e) \propto rate\ of\ change\ of \ Magnetic\ Flux\ (\phi _b)}$

$\sf {and\ \phi_b = B\ ^. A = BAcos\ \theta}\\\\\\\sf {Here\ B \perp A \Rightarrow \phi_b = BACos\ 90^o = 0}$

$\fbox {So, Induced emf = 0}$

Hence, a change in current of wire will not create any emf in the loop.
