Solution
The correct options are A The emf induced in the loop is zero if the current is constant. C The emf induced in the loop is zero if the current decreases at a steady rate. emf induced in coil is 0 if the current is constant because there is no changing flux
ε=−Ndϕdt
Emf induced in the loop is finite if the current decreases at a steady state.
