Question

The strength of induced voltage in rotating coil depends mostly on

Answer 1

Answer:

The more turns of wire, the stronger the field produced. Conversely, a changing external magnetic flux induces a voltage in a conductor such as a wire, due to Faraday's law of induction. The induced voltage can be increased by winding the wire into a coil, because the field lines intersect the circuit multiple times.

Answer 2

Answer:

Magnetic strength of the core in the coil of wire. (stronger --> bigger emf) Number of turns of wire in the coil (more turns --> bigger emf) The cross-sectional area of the coil (bigger area --> bigger emf).
