Question

what is essential for inducing a current in a conducting wire using a magnetic field?​

Answer 1

Answer:

A changing magnetic field through a coil of wire therefore must induce an emf in the coil which in turn causes current to flow. ... A is the area vector; its magnitude is the area of the loop, and its direction is perpendicular to the area of the loop, and q is the angle between A and the magnetic field B.
