electromagnetic force Scientific  

/ ĭ-lĕk′trō-măg-nĕt′ĭk /

1. The fundamental force associated with electric and magnetic fields. The electromagnetic force is carried by the photon and is responsible for atomic structure, chemical reactions, the attractive and repulsive forces associated with electrical charge and magnetism, and all other electromagnetic phenomena. Like gravity, the electromagnetic force has an infinite range and obeys the inverse-square law. The electromagnetic force is weaker than the strong nuclear force but stronger than the weak force and gravity. Some scientists believe that the electromagnetic force and the weak nuclear force are both aspects of a single force called the electroweak force.

"Theoretically, it interacts with gravity, but it has no interaction with the others, weak nuclear force, strong nuclear force or electromagnetic force," Sousa said.

The electromagnetic force is long range because the photon has no mass, and the weak force is short range because the particles that convey it, the W and Z, are massive.

At extremely high energies, the electromagnetic force, which controls the behavior of charged particles such as electrons, and the weak force, which governs processes such as fission decays, are unified into one “electroweak” force.

As the outer core's fluid motion generates a magnetic field for our planet, that same magnetic field drives the metallic inner core to rotate through electromagnetic force.

Thus the attractive and repulsive forces between the individual particles nearly cancel each other out, and there is very little net electromagnetic force.
