What is a moving fee?

Movement is an informal way to refer to a charged object that changes its position with respect to a particular observer. Moving fees differs significantly from stationary in that they generate magnetic fields. Since the object can move due to one observer and remain stationary with respect to the other, it is possible for different observers to measure different values ​​for the same magnetic field. This observation was one motivation that led Albert Einstein to formulate her special theory of relativity in 1905. When the wire is connected to the battery, the electric field maintained by the battery naturally causes the electrons in the wire. While the electrons are responsible for carrying hubs along the wires, larger ions move inside the battery. Negative ions move from the positive battery terminal to its negative terminal and positive ions move in the opposite direction. In this way, the ACTS battery is pushing the current around the perimeter.

the movement of the charge in the circuit generatesmagnetic field. Although pupils often have the impression that the power of the electrical circuit lies in the movement of electrons in the wire, the usefulness of the perimeter in all the most basic applications is found in the electromagnetic fields produced. Modern technology uses these fields in countless ways, especially to supply electromagnets critical for the operation of electric motors.

moving charges are not only the cause of magnetic fields, but are also affected by them. The magnetic field causes a curve of a moving charge, and the greater its speed, the more the magnetic field strength develops on a moving charge. In this way, the current in one circuit can affect the current in the other. Transformers use this effect and use the current in one wire to create another act in another. Electric power plants use a variant of this idea to produce electricity.

electrically charged particles develop strength to othersHo, so work is necessary to move one with respect to the other and in the absence of magnetic fields. The work needed to build hubs is equal to the electrical energy of the system. Two positively charged objects repel each other, and the efforts needed to push them can be compared to the energy needed to compress the spring. The battery can be qualitatively seen as a few such sources and the chemical reactions inside the battery cause charging as a sign at both ends.
