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

Options

A. The `emf` induced in the loop is zero if the current in constant.
B. The `emf` induced in the loop is infinite if the current in 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 infine if the current decreases at a steady rate.

Answer

A, C

Explanation

`(phi)_("loop")=0` for all cases so induced `emf=0`
