How is electromagnetic force unlike the other three forces?

The electromagnetic force is a special force that affects everything in the universe because (like gravity) it has an infinite range. It has the ability to attract and repel charges. Since material in solid and liquid forms are made of charges having a unique order, they, too, may be manipulated by this force. It is also responsible for giving things strength, shape, and hardness. The electromagnetic force can be generated by three types of fields known as the electrostatic field, magnetostatic field, and the electromagnetic field. Some of Earth's greatest philosophers brilliantly used the concept of field lines to help visualize how one object can be moved by another object without actually touching each other. Wow! . . . Force at a distance! Let's see. . .how does this work? Oh, yes, of course! The field lines for static fields are tied to the sources. Static means that the strength and orientation of the source does not change with time. Static electric fields originate from a positive charge and terminate on a negative charge. Static magnetic fields circulate around moving charge (or charges) sometimes called current. They have no beginning or end; they circulate. Because these fields are tied to sources, when the sources are turned off, the field lines disappear and no force is felt. Did you know that the electromagnetic force is responsible for you to have the ability to hold and move things such as your mouse? The electrostatic fields generated among the atoms and molecules near the surface of your hand generate a force field that doesn't allow large objects to pass through your hand. Now you have it! The electrostatic force is responsible for dirt sticking on your hand!
