Charges are produced due to a source providing some energy. e.g cell. Firstly source creates potential difference between terminals and due to this electron at negative end of the terminal move towards positive terminal. In contrast, conventional current flows from positive to negative.
In AC circuit electron stay at same place and just vibrate and energy is just passed around the circuit.
An electric current is produced when charges are accelerated by an electric field and move to a position of potential energy difference. This movement of charges generates a flow of electric charge that constitutes an electric current.
When charges move along a path, an electric current is produced. This flow of electric charge can result in the generation of a magnetic field around the path of the moving charges. The relationship between electric current and magnetic fields is described by the laws of electromagnetism.
Electric Current
The basis for this statement is the concept of electric field lines originating from positive charges and terminating on negative charges. This is in accordance with the fundamental property of charges where opposite charges attract each other. Therefore, electric field lines cannot start or end in empty space, as they always originate from and terminate on charges.
All magnetism is due to circulating electric currents or motion of electric charge. In magnetic materials the magnetism is produced by electrons orbiting within the atoms; in most substances the magnetic effects of different electrons cancel each other out, but in some, such as iron, a net magnetic field can be induced by aligning the atoms.
Current is produced when charges are accelerated by an electric field to move to a position of lower energy.
Electric fields are created by electric charges and exert forces on other charges, while magnetic fields are created by moving electric charges and exert forces on other moving charges. In summary, electric fields are produced by stationary charges, while magnetic fields are produced by moving charges.
Electric fields are created by electric charges and exert forces on other charges, while magnetic fields are created by moving electric charges and exert forces on moving charges. Electric fields are produced by stationary charges, while magnetic fields are produced by moving charges. Additionally, electric fields can be shielded by conductive materials, while magnetic fields can penetrate most materials.
An electric current is produced when charges are accelerated by an electric field and move to a position of potential energy difference. This movement of charges generates a flow of electric charge that constitutes an electric current.
An electric field E is produced by a punctual electric charge q or by any electrically charged object. The Efield produced by a charge is analogous to the gravitational field g produced by a mass : Fg= mg the same way Fe = qE.
An electric charge is produced when a body has deficiency or excess of electrons from the normal due share.
In an electric field with multiple charges, the lines of force point away from positive charges and towards negative charges. The lines of force follow the direction of the electric field, which is a vector sum of the individual electric fields produced by each charge.
A magnetic field is produced by moving electric charges. When electric charges move, they create a magnetic field around them. This magnetic field can interact with other magnetic fields and cause objects to be attracted or repelled.
Yes, an electric field can exist without a magnetic field. Electric fields are produced by electric charges, while magnetic fields are produced by moving electric charges. So, in situations where there are stationary charges or no current flow, only an electric field is present.
lower than their initial potential energy. The charges gain kinetic energy as they accelerate through the field, creating an electric current.
Electromagnetic fields are a combination of electric and magnetic fields that oscillate and propagate through space, carrying energy. Magnetic fields, on the other hand, are produced by moving electric charges and exert forces on other moving charges. In summary, electromagnetic fields involve both electric and magnetic components, while magnetic fields are solely produced by moving electric charges.
The electric field strength exactly midway between two equal charges is zero. This occurs because the electric fields produced by the two charges cancel each other out at that point due to their opposite directions.
