A current carrying infinitely long wire ...

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)

A

(a) The emf induced in the loop is zero if the current is constant

B

(b) The emf induced in the loop is finite if the current is constant

C

(c ) The emf induced in the loop is zero if the current decrases at a steady rate.

D

(d) The emf induced in the finite if the current decreases at a steady rate.

Text Solution

Verified by Experts

The correct Answer is:
A, C
`(phi)_(loop) = 0` for all cases
`So induced emf = 0`
