Question 43: Electromagnetic Induction

Question

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)

Accepted Answer

The magnetic field due to an infinitely long conductor is circumferential.
Since this conductor is placed along the diameter of circular loop (see figure), the total magnetic flux through the circular wire loop is always zero.

Answer

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

Answer

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

Answer

the emf induced in the loop is zero if the current decreases at a steady state

Answer

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