Question

why we coil the wire​

Answer 1

Answer:

An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil, spiral or helix. ... 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.

Answer 2

as coil is a electrical insulater which helps the wire to hold shape and reduces risk it follows the faraday's law of induction

plss mark me as brainleist :-)
