Why do electric charges that move through a magnetic field produce an electric current? A. The magnetic field exerts a force on
only the negative charges in the wire. B. The magnetic field pushes negative charges and positive charges in opposite directions. C. The magnetic field pushes negative charges and positive charges in the same direction. D. The magnetic field exerts a force on only the positive charges in the wire.
Kinetic energy is the energy of mass in motion, the kinetic energy that an object has is because of it's motion.Heavier objects that are moving have more kinetic energy than lighter ones.
