Electric Field and Magnetic Field

When a charge is present in any form, a field is created around each point in space, and this field is known as an electric field. The value of E, also known as electric field strength or electric field intensity, or simply the electric field, is used to represent the magnitude and direction of the electric field. Electric charges in motion form a magnetic field. The presence of iron in close proximity to this field causes it to exert a force on the substance. In a vacuum, a magnetic field can be generated and propagated. As a result, the magnetic field has a bigger energy storing capacity than the electric field, which is why it is used in nearly every electromechanical device, including transformers, motors, and even generators, because of this.

Electric field 

When an electric charge is present, it creates an electric field around it, which acts as a force multiplier on all other charges as well. It’s either drawing them in or driving them away. E-field is a common abbreviation for the electric field. Electrostatic or Coulomb force/unit of charge exerted on an infinitesimal positive test charge resting at a given place in space is characterized mathematically as a vector field. Electric field strength is measured in volts/meters. (V/m). The electric field strength unit Newtons/coulomb (N/C) is also relevant. Electric charges or time-varying magnetic fields generate electric fields.

An electric charge, or a collection of electric charges, will produce an electric field in its vicinity. Any charged object that is placed in this field will experience an electrostatic force as a result of the interaction between the field and the charge of the object.  Field lines show the force that a positively charged particle would experience if it were to be in the field at that particular point in time.

The movement of electric charges can also be caused by a changing magnetic field. This phenomenon is often applied in electric generators to produce electric currents in wires, which is useful for generating electricity. Larger changes in a magnetic field, as well as coiling the wire, can both enhance the induced current. Coiling the wire allows for a greater amount of wire to be impacted by the changing magnetic field.

Magnetic field 

The magnitude and direction of the magnetic field are both vector quantities (i.e., they both have a magnitude and a direction), and the magnetic field’s direction is from the north pole to the south pole. In the presence of magnetic field lines, closed curves are always formed, and the strength is determined by how close the magnetic field lines are to one another. When the magnetic field lines are closer to the magnetic material, they are closer to one another; when they are further away from the material, they are farther away from one another.

In the end, magnetic fields are produced by the movement of charged particles. When the current is flowing via a straight wire, we can see the magnetic field that surrounds it as it moves. We take advantage of this phenomenon to power motors and even to store information in computer hard drives and memory.

It is possible to enhance the magnetic field surrounding a current-carrying wire by coiling the wire and/or increasing the current that flows through it. In a magnetic field, the field lines represent the force that would be experienced by a magnet on its north side if it were in the field at that particular location.

Difference between electric field and magnetic field 

Relation between electric field and magnetic field formula 

The formula F = (E + v B) tells the relationship between electric and magnetic fields. In accordance with the constitutive relations, the electric displacement D and magnetic intensity H are related to the electric field and magnetic flux density by the formulas: D= E, B= H.

Conclusion 

Electric charges or time-varying magnetic fields generate electric fields. E-field is a common abbreviation for the electric field. Electric field strength is measured in volts/meters. The electric field strength unit Newtons/coulomb (N/C) is also relevant. Magnetic fields are produced by the movement of charged particles. In a magnetic field, the field lines represent the force that would be experienced by a magnet on its north side if it were in the field at that particular location. The magnitude and direction of the magnetic field are vector quantities.
