Answer: Option (C) is the correct answer.
Explanation:
It is known that current is the flow of electrons or electric charges.
And when electric current flows through a wire or material then it generates a magnetic field outside the material.
Mathematically, B = [tex]\frac{\mu_{o} I}{2 \pi r}[/tex]
where B = magentic field
[tex]\mu_{o}[/tex] = magnetic permeability
r = radial distance
Therefore, we can conclude that a magnetic field is created by a charged particle that is moving.
