A current carrying infinitely long wire is kept along the diameter of a circular wire loop,without touching it. The correct statement (s) is (are) :

A

the emf induced in the loop is zero if the current is constant.

B

The emf induced in the loop is finite if the current is constant.

C

The emf induced in the loop is zero if the current decreases at a steady rate.

D

The emf induced in the loop is finite if the current decreases at a steady rate.
