Hint: Whenever current flows in a cable, it will generate a magnetic field according to Maxwell’s laws. This property of a material to generate a magnetic field when current flows through it is called electromagnetism.
Complete step-by-step answer: A current-carrying coil behaves likes a magnet when a current is passed through it. This property of conductors is called electromagnetism.
There are a number of factors that influence the strength of the magnetic field that will be generated by the current-carrying coil.
1) The number of turns directly affects the strength of the magnetic field that is generated. The higher the number of coils in the current-carrying coil, the higher the magnetic field.
2) The current flowing in the coil will also directly affect the magnetic field. The higher the current the more is the strength of the magnetic field and the lower the current the lower is the strength of the magnetic field.
3) The third factor is the kind of material that the wire is composed of. The less the resistance of the wire, the higher the current will flow in the circuit and the higher the magnetic field.
Hence, to increase the magnetic field, we can increase the number of turns of the wire in the coil.
Note: The formula of the magnetic field due to a circular coil at its centre is given as
$B = \dfrac{{{\mu _0}nI}}{{2R}}$ where $n$ is the number of turns, $I$ is the current, and $R$ is the radius of the circular coil. As we can see, if we increase the number of turns, the magnetic field will also increase.
