Amagnetic field is created by a charged particle that is a) balanced. b) motionless. c) moving. d) unbalanced.

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 =

where        B = magentic field

        = magnetic permeability

                   r = radial distance

Therefore, we can conclude that a magnetic field is created by a charged particle that is moving.
