3. all changed objects exert n force that can cause other charges to move. What is the force that off called? What else can it do? o

The force that all charged objects exert on other charged objects, causing them to move, is called the **electromagnetic force** (often referred to as the **electric force** when dealing with static charges).<br /><br />Besides causing charged objects to move, the electromagnetic force can also:<br /><br />* **Attract or repel other charged objects:** Like charges repel each other (positive repels positive, negative repels negative), while opposite charges attract each other (positive attracts negative).<br />* **Create electric fields:** A charged object creates an invisible field around itself that influences other charged objects within the field.<br />* **Produce electric current:** The movement of charged particles, often electrons, constitutes an electric current. This is the basis for how electricity works in our homes and devices.<br />* **Generate magnetic fields (when charges are in motion):** Moving charges create magnetic fields, and magnetic fields can in turn exert forces on moving charges. This interplay between electricity and magnetism is the foundation of electromagnetism.<br />* **Produce electromagnetic radiation:** Accelerating charges produce electromagnetic waves, which include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.<br /><br /><br />It's important to note that the electromagnetic force is one of the four fundamental forces in nature, along with the strong nuclear force, the weak nuclear force, and gravity. It plays a crucial role in the structure of atoms and molecules, and in many everyday phenomena.<br />
