Respuesta :

When an electric charge is in motion, it creates an electric field and a magnetic field around it. This magnetic field exerts a force on any other electric charge that is located within its radius of action. This force exerted by a magnetic field will be the electromagnetic force.

Charges in motion are called current, therefore, the answer is:

D. have a current flowing through it.
