Answer:
The magnetic field produced by a single wire loop will have a definite direction and strength. If we increase the number of loops the magnetic field due to each loop will add. ... Therefore, the magnetic field of a current-carrying coil having n turns is 'n' times as large as produced by a single loop.

The magnetic field is directly proportional to the current in the wire loop, with each loop the current increases and so the magnetic field increases. ... Therefore, the magnetic field of a current-carrying coil having n turns is 'n' times as large as produced by a single loop.
