Answer:
Option C. is correct
Explanation:
The magnetic field is the area around a magnet in which there is magnetic force. When an electric current flows through a wire a magnetic field is created. A single wire does not produce a strong magnetic field. So, to increase the power of the magnetic field, increase the number of coils in the wire.

If it were possible to give that information over in a few paragraphs or a few mimutes, then you'd see little stores everywhere, where you could drop in for an hour or an afternoon, pay a few bucks, and learn Physics. You don't, because you can't, because it isn't.
Here are a few things you definitely need. But I have to tell you: If you don't put time and effort into learning them, they won't do you much good.
==> F=m a. ==> Total mass is conserved. ==> Total energy is conserved. ==> Everything falls at the same rate. ==> Sound needs material to travel through. Light doesn't. ==> Light, radio, heat, X-rays, and ultraviolet radiation are all the same thing. ==> It takes force on an object to make it speed up, slow down, or curve. A moving object with no force acting on it keeps going in a straight line at the same speed forever. ==> Gravity attracts every speck of mass in the universe to every other speck. The forces of attraction are greater when the masses are greater and closer together.
