Best answer: What are the 2 properties of an electric field?

What are the properties of electric field?

Properties of Electric Field Lines

  • The field lines never intersect each other.
  • The field lines are perpendicular to the surface of the charge.
  • The magnitude of charge and the number of field lines, both are proportional to each other.

What are the 2 sources of electric fields?

The electric field is produced by stationary charges, and the magnetic field by moving charges (currents); these two are often described as the sources of the field. The way in which charges and currents interact with the electromagnetic field is described by Maxwell’s equations and the Lorentz force law.

What are the four properties of electric field lines?

In an uniform electric field, the field lines are straight, parallel and uniformly spaced. The electric field lines can never form closed loops, as line can never start and end on the same charge.

What are two properties by which electric potential is related to the N electric field?

(i) The magnitude of electric field intensity is numerically equal to potential gradient. (ii) Negative sign signifies the electric field intensity is in the direction of decreasing electric potential gradient.

What are the two basic properties of electric charge?

There are very two basic properties of electric charge. They are: Similar electric charges tend to repel each other. Opposite electric charges tend to attract each other.

What are the properties of field?

Mathematicians call any set of numbers that satisfies the following properties a field : closure, commutativity, associativity, distributivity, identity elements, and inverses.

What are electric fields made of?

Electromagnetic fields are made out of photons. The magnitude and direction of the electromagnetic field intensity at any point is directly proportional to the magnitude and direction of the force of the photon at that point.

What is electric field and electric field intensity?

What is Electric Field Intensity? The space around an electric charge in which its influence can be felt is known as the electric field. The electric field intensity at a point is the force experienced by a unit positive charge placed at that point. Electric Field Intensity is a vector quantity. It is denoted by ‘E’.

What is electric field Class 12?

Electric field is a force produced by a charge near its surroundings. This force is exerted on other charges when brought in the vicinity of this field. … Electric field due to a charge at a point is the force that a unit positive charge would experience if placed at that point.

Can two electric field lines intersect?

Electric field lines cannot cross. If they did, they would be telling you that the force on a charge at that location would point in two different directions, which does not make any sense at all. … Note: It is possible for two lines representing the same potential to cross.

Why do two field lines never intersect?

The magnetic field lines never intersect each other because if two or more lines intersect each other than it means that at that point of intersection, the magnetic field has two directions at the same point. This is not possible for a magnetic field to point in more than one direction at the same point.

What are the properties of electric charge?

Some other properties of electric charge

Charge is a scalar quantity. Charge is transferrable, they transfer from one body to another. Like charges repel each other and unlike charges attract each other. Charge is always associated with mass.
