Electric and magnetic fields

In the universe, magnetism has a great importance as most of the heavenly objects are influenced by the magnetic fields. The planet earth has also a constant magnetic field around it, as the magnet has a north and south poles; the earth has also the north and south poles. These poles were being in use from many years and people find their ways and directions utilizing the earth magnetic poles. Magnetic and electric fields are utilized to generate electrical power. Similarly, electric and magnetic fields are utilized to convert the electrical energy into mechanical energy by the utilization of a motor.
A field of physics is dedicated to study the electric field that is Electrostatics. Electrostatics studies the electric field in relation with the electric flux, electric potential energy, electric potential, electrostatic induction and electric dipole movement. Electric field is a vector quantity having no fixed direction and has the units of N/C (Newton per Coulombs) or V/m (Volt per meter). The field is produced due to the movement of the electrical charged particles. The movements of the charged particles produce a magnetic field. The magnetic and electric fields are such linked to each other that one influences the other. In this way, the electric fields can be described by force that a charged test particle face. The force directs the electric fields in the similar direction as that of the force (Oatley 5-27). In this perspective the idea of electromagnetism grown and referred as the field dealing with both the quantities.
Magnetic field is termed to be vector; the field has a direction and magnitude. The movement of the electrical charge produces the magnetic fields (Herlach & Miura 1-65). In this way, electrical charge or the charged particles highly influence the magnetic field. Magnetic fields are much important in determining the direction on the ship along with the most modern system like GPS (Global positioning system). Changing the magnetic ...Show more

Summary

The electric field is a field around any electrical charged body or a body that is influenced by the charged particles. The charged particles maintain a constant field around them and if a metallic object id placed within…

Conversion of Energy
Another way is through the atomic emission and absorption of light photons to generate photothermal effect producing thermal energy that converts photon’s energy to molecular vibrations, photoelectric effect that yields electrical energy from kinetic energy, and photochemical effect that renders storage of energy out of chemical changes.

Magnetic Geophysical Method
The magnetic geophysical method is a scientific approach that is used to measure variations or anomalies that are localized and small in the magnetic field of the earth. Materials found on the surface of the earth such as the basic igneous rocks, and the ore magnetic bodies are helpful when it comes to the identification of the magnetic variations because they have the magnetic properties.

Electric and Magnetic Fields
The charged particles maintain a constant field around them and if a metallic object id placed within the range of the field, it will react or a person that id holding the metallic object might get a little shock. A field is lines of forces that are made by the charged particles.

The Relationship Between Magnetism and Electricity by Bidisha Mukherjee
The article by Bidisha Mukherjee, “The Relationship Between Magnetism and Electricity”, discusses the link between electric and magnetic fields, and the way one can be produced and effected by the other. It states that a changing electric field, or electric field in motion, called electricity, produces a magnetic field.

X-ray Photons
Monochromatic beam of X-ray photons is directed perpendicularly to the electric and magnetic fields. For simplicity they often consider the electric field only and neglect the magnetic field. From a quantum mechanical perspective a monochromatic beam is viewed as being quantised onto photons each having an energy and momentum.
