Difference between electric field and magnetic field

The main difference between the electric field and the magnetic field is that the electric field is produced around the static charge particles that are negative or positive, while the magnetic field is an area exerted around the magnetic force obtained by the movement of charges. electrical. The major difference between the electric and magnetic field is that the electric field induces around the particle of static charge that is negative or positive, while the magnetic field produces around the poles (that is, the north and south poles). of the magnet. Some other differences between them are explained below in the form of a comparison table.

  • Electric field produced around the static charge particles that is negative or positive, while the magnetic field is an area exerted around the magnetic force obtained by the movement of electric charges.
  • Both electric and magnetic fields are vector quantities, since they have magnitudes and directions.
  • Both the electric and magnetic fields create an “electromagnetic field” and the motion of the electric field in an electromagnetic field is perpendicular to the magnetic field, while the motion of the magnetic field in an electromagnetic field is perpendicular to the electric field.
  • The electric field can be monopole or dipole, while the magnetic field is the only dipole.
  • The force produced by the electric field is proportional to the electric charge, while the force produced by the magnetic field is proportional to the charge and the speed of the electric charge.

Electric field vs magnetic field – Overview

The electric field is produced around the static charge particles that are negative or positive, while the magnetic field is one exerted around the field that has a magnetic force due to the movement of electric charges. The electric field does not rest on the magnetic field, and like the magnetic field, it does not depend on the electric field.

In the electric field, the electromagnetic field generates VARS (Capacitive), on the contrary, in the magnetic field, the electromagnetic field absorbs VARS (Inductive).

The electric field can be monopole or dipole, while the magnetic field is the only dipole. The force produced by the electric field is proportional to the electric charge, while the force produced by the magnetic field is proportional to the charge and speed. of the electrical charge. The electric field does not form a closed circuit while the magnetic field forms a closed circuit.

The unit of the electric field is volt/meter or newton/coulomb, while the unit of the magnetic field is Tesla. The electric field is denoted by E, while B denotes the magnetic field.

What is the electric field?

The force around particles of static electric charge, either positive or negative, is called the electric field. An electric field occurs wherever a voltage exists. The electric field is generated around electrical appliances and cables where there is voltage.

The electric field has both magnitude and direction. So it is a vector quantity. ME symbolizes the electric field. The unit of the electric field is Volt/meter or Newton/coulomb. The strength of an electric field decreases as we move away from the source.

It can exist independently as in the absence of a magnetic field; there is an electric field in the form of static electricity. Both the electric and magnetic fields create an “electromagnetic field” and the movement of the electric field in the electromagnetic field is perpendicular to the magnetic field.

In the electric field, the electromagnetic field generates VARS (capacitive). The electric field can be monopole or dipole. The electrometer measures the electric field. Many objects protect electric fields, such as trees or the walls of buildings.

The force around the particle of electric charge is called the electric field or electric field intensity. In other words, it is an area around the electric field where the line of force exists. It has magnitude and direction. Therefore, it is a vector quantity. The symbol E expresses the electric field and is measured in newton/coulomb.

What is a magnetic field?

The magnetic field is an area that is exerted around the magnetic force obtained by moving electrical charges. The magnetic field has a south pole and a north pole. The magnetic field is created when electric currents are present. As the amount of current flowing increases, the level of the magnetic field increases.

The appearance and strength of a magnetic field are indicated by “magnetic flux lines” obtained by electric charges. These lines also indicate the direction of the magnetic field.

The closer the lines are, the stronger the magnetic field and vice versa. The magnetic field is also a vector quantity, so it has a direction and a magnitude. B symbolizes the magnetic field. Its unit is Tesla (Newton * Second) / (Coulomb * Meter). We measure the magnetic field in milliGauss (mG).

The magnetic field does not depend on the electric field. It can exist independently as in the absence of an electric field; the magnetic field exists in permanent magnets. In the magnetic field, the electromagnetic field absorbs VARS (inductive). The magnetic field is the only dipole.

The magnetic field forms a closed circuit. The magnetic field cannot work because the speed of the particles remains constant.

The region around the magnetic where its poles exhibit an attractive or repulsive force is called the magnetic field. The magnetic field also induces when electric charges move in space or an electric conductor. The moving charge carrier and the magnet produce lines of magnetic flux, and these lines are called magnetic field lines. It is a vector quantity because it has both magnitude and direction. The symbol B expresses the magnetic field and is measured in Tesla or Newton per meter.

Conclusion

The above discussion concludes that the electric field is produced around the statically charged particles, while the magnetic field is an area exerted around the magnetic force obtained by moving electric charges. The charge induces the electric field, and the magnetic field induces due to the north and south pole of the magnet.
