Electricity is defined as the presence and flow of electric charge, which involves the interaction between positively and negatively charged particles. The relationship between electricity and magnetism is fundamental, as a changing electric field generates a magnetic field, and vice versa. This interplay is governed by the electric force, which describes how charged particles attract or repel each other. The concept of the electric field is crucial, as it represents the force exerted by a charged particle on other charges in its vicinity. Understanding these principles is essential for grasping the nature of electricity and its connection to magnetism.
